If you’ve ever flown into San Diego International Airport, you’ve seen it. Those two massive towers sitting right on the water, practically close enough to the runway that you could wave at the pilots. That’s the Sheraton San Diego Hotel and Marina. It’s a landmark. But honestly, it’s also a bit of a polarizing spot for travelers who can’t decide if they want the convenience of the airport or the vibe of a true resort.
Most people book this place because they see "Marina" in the name and assume they’re getting a quiet, nautical escape. Others book it because they have a 6:00 AM flight and don't want to deal with downtown traffic. Both are right, kinda. But there is a lot more going on behind those glass doors than just a place to crash before a flight. The property recently underwent a massive, multi-million dollar renovation, specifically targeting the Marina Tower, and it has fundamentally changed how the hotel feels. It’s less "90s corporate hub" and more "modern coastal retreat" now.
What's Actually New After the Renovation?
Let's talk about the money. Sheraton (under the Marriott umbrella) poured a staggering amount of cash into the Marina Tower. If you stayed here three years ago, forget what you saw. The lobby used to be a bit dark and cramped. Now? It’s wide open. They’ve implemented the "Community Hub" concept, which basically means they want you to hang out in the lobby with your laptop and a $7 latte.
The rooms in the Marina Tower are the real winners. They went for a soft, coastal palette—think light woods, blues, and greys that actually mimic the water outside. The bathrooms were the biggest pain point in the past, and most have been stripped down and modernized. However, a pro tip: the Bay Tower (the second building) hasn't always matched the pace of these updates. If you want the "new hotel smell," you have to specify the Marina Tower.
The dining scene got a total overhaul too. Rumorosa is the standout. It’s a "Cali-Baja" inspired kitchen. It’s not just a hotel restaurant where they serve lukewarm Caesar salads. They’re actually doing interesting things with aguachile and local sea bass. It feels like a place a local might actually drive to for dinner, which is the highest compliment you can pay a hotel restaurant on Harbor Island.

The Location Logic: Harbor Island vs. Downtown
You need to understand where this hotel sits. It’s on Harbor Island. This is a man-made peninsula. You are surrounded by water on both sides. To the north, you have the airport fence and the San Diego Bay; to the south, you have the marina and the skyline.
It’s isolated. That’s the catch.
You aren't walking to the Gaslamp Quarter from here. You aren't walking to Little Italy. If you want to go anywhere, you’re calling an Uber or hopping on the shuttle. But—and this is a big but—the view of the San Diego skyline from the Sheraton San Diego Hotel and Marina is arguably the best in the city. Because you’re looking back across the water at the skyscrapers, the perspective is incredible, especially at night.
The Airport Factor
Yes, it is loud. It's right next to an international airport. The planes take off frequently. However, the hotel used some high-grade soundproofing in the recent refresh. If the balcony door is shut, it’s surprisingly quiet. But if you’re sitting at the pool? You’re going to hear the roar. Some people find it cool to watch the planes; others find it annoying. It just depends on whether you’re a closet aviation nerd or someone who needs total silence to enjoy a piña colada.

Swimming, Sailing, and Logistics
There are three pools here. Three. That’s a lot of real estate. The main pool at the Marina Tower is the "see and be seen" spot, usually packed with families and people drinking at the pool bar. If you want something quieter, you head over to the Bay Tower pool. It’s usually much more chill.
The "Marina" part of the name isn't just for show. You can actually rent stuff.

- Sailboats
- Jet skis
- Paddleboards
You can literally walk out of the lobby and be on a boat in five minutes. This is where the hotel wins over the downtown Marriotts or Hyatts. Those hotels are near the water, but the Sheraton is on the water. There is a specific smell of salt air and boat fuel that hits you the moment you walk out the back doors. It feels like vacation.
Why Business Travelers Still Rule the Roost
Despite the resort vibes, this is a massive convention hotel. If there is a medical conference or a tech summit in town, this place swarms with lanyards. The meeting space is cavernous—over 130,000 square feet.

The Sheraton Club Lounge is one of the better ones in the Marriott system, specifically because of the view. If you have Platinum status or higher, or if you pay for the upgrade, it’s worth it. They do a solid breakfast spread and evening hors d'oeuvres. It’s a quiet sanctuary when the main lobby gets chaotic during check-in at 4:00 PM.
One thing that trips people up: the parking. It’s expensive. Actually, it’s painful. You’re looking at $40 to $50 a day depending on if you self-park or valet. Since you’re on an island and have to drive everywhere, that cost adds up fast. If you can get away with using rideshares, you’ll save a fortune.
Getting the Most Out of Your Stay
Most people just check in and stay in their rooms. Don't do that. There is a walking path that circles Harbor Island. It’s about 2.5 miles round trip. If you go at sunrise, you’ll see the Navy ships heading out to sea and the sun hitting the downtown glass. It’s one of the most underrated walks in San Diego.
Also, check the shuttle schedule. The hotel runs a free shuttle to the airport, but they also have a shuttle that can take you to certain nearby spots. It saves you $15 on an Uber if you time it right.
Common Pitfalls to Avoid
- The "Resort Fee": Like almost every major San Diego hotel now, there’s a daily resort fee. It covers things like the shuttle, internet, and some rentals. Don’t be surprised when your checkout bill is $35-45 higher per night than the base rate you saw on Expedia.
- Room Choice: If you get a "Limited View" room, you’re likely looking at the parking lot or the airport fence. It’s worth the extra $30 to get the Marina view. It changes the entire mood of the trip.
- Dining Off-Site: You’re not stuck at the hotel. Island Prime and C-Level are two very famous (and very good) restaurants right down the street on Harbor Island. They’re within walking distance and offer a different vibe than the hotel bars.
Actionable Takeaways for Your Visit
If you’re planning a stay at the Sheraton San Diego Hotel and Marina, keep these specific steps in mind to ensure you don't end up frustrated:
- Book the Marina Tower: Always verify your room is in the renovated Marina Tower rather than the Bay Tower unless you specifically want a quieter, older vibe.
- Join Marriott Bonvoy: Even if you aren't a frequent traveler, the "member rate" usually offsets the cost of the resort fee, and it makes getting a late checkout much easier.
- Download a Flight Tracker: Since you’re so close to SAN, it’s actually pretty fun to use an app like FlightRadar24 while sitting on your balcony to see where the planes are headed.
- Use the Path: Carve out 40 minutes for the Harbor Island trail walk. It’s the best free amenity the hotel has, even if they don't "own" it.
- Check the Convention Calendar: Before booking, Google "San Diego Convention Calendar." If there’s a 5,000-person event at the hotel during your dates, the elevators and pools will be slammed. If it’s an "off" week, you’ll have the place to yourself.
The Sheraton isn't trying to be a boutique hotel in the Gaslamp. It’s a massive, efficient, scenic machine. If you go in knowing that it's a bit of a trek to downtown but offers the best views and water access in the city, you’ll have a much better time. Just watch out for those parking fees—they're the only thing that might ruin the sunset.
