You’re landing in San Juan. The humidity hits you the second you step off the plane at Luis Muñoz Marín International (SJU), and honestly, the last thing you want to deal with is a rental car nightmare. We’ve all been there. You stand in a fluorescent-lit line for forty minutes only to find out the "economy" car you booked is actually a beat-up sedan from 2018 with a sticky steering wheel.
Alamo car rental San Juan operates a bit differently than the scrappy off-airport startups that lure you in with a $12-a-day rate only to hit you with $40 in mandatory insurance fees later.
Puerto Rico is a driving island. If you stay in Old San Juan, sure, you can walk. But if you want to see the bioluminescent bay in Fajardo or hike El Yunque, you need wheels. Alamo is part of the Enterprise Holdings family, which also includes National and Enterprise. This matters because they share a massive fleet. If Alamo runs out of a specific mid-size SUV, they can often pull from the sister brands right there on the lot.
The SJU Airport Reality Check
When you book Alamo car rental San Juan, you aren't hopping on a sketchy, unbranded shuttle to a lot ten miles away. They are located right in the parking garage across from the terminals. You walk. It's that simple.
Most people don't realize how much of a time-saver this is. In Puerto Rico, traffic around the airport can become a complete standstill during rush hour. If your rental agency is off-site, you’re gambling with a 30-minute shuttle ride just to get to the desk. Alamo’s counter is in the Main Terminal (Terminal B/C arrivals area).
How the "Skip the Counter" System Changes Your Life
Look, nobody wants to talk to a human after a four-hour flight. Alamo’s "Skip the Counter" feature is probably their biggest selling point. You check in online, enter your driver’s license info, and head straight to the garage. You pick a car in your category, drive to the booth, show your ID, and leave.
It works. Mostly.

Sometimes, during peak holiday weeks—like the dreaded Christmas to Three Kings Day stretch—the "skip" line can still have a bottleneck at the exit booth. But compared to the 50-person deep line at the budget counters downstairs? It’s a win.
What Kind of Car Do You Actually Need?
Don't just click the cheapest option.
If you are planning to stay in the metro area or stick to the PR-22 highway towards Dorado, a Nissan Versa or similar compact is fine. It’s easy to park in the tight spots of Condado. However, if your itinerary includes the central mountains or the steep, winding roads of Utuado, get something with a bit more torque. You don't necessarily need 4WD unless you’re staying at a very specific remote Airbnb, but a small SUV (like a Toyota RAV4 or Ford Escape) makes the potholes of Puerto Rico much more manageable.
Those potholes are legendary. They aren't just dips; they are craters. A low-clearance sedan will make you wince every time you hit a puddle that’s deeper than it looks.
Insurance: The Puerto Rico Quirk
Here is the thing about Alamo car rental San Juan and insurance. Puerto Rico is a U.S. territory, so your domestic car insurance often carries over. But—and this is a big "but"—you need to call your provider and confirm.
- CDW (Collision Damage Waiver): This is what they’ll try to sell you at the desk. If you have a premium credit card like the Chase Sapphire Reserve or the Amex Platinum, you likely have primary rental coverage. Use it.
- SLP (Supplemental Liability Protection): Your personal US auto policy might cover liability in PR, but many don't. Check.
- The Tolling Situation: This is where they get you. Puerto Rico’s highways use "AutoExpreso." Most Alamo cars come with a transponder. You’ll be charged a daily fee plus the tolls. You can’t really avoid this because many toll plazas don't even take cash anymore. It’s annoying, but it beats getting a $100 fine from the Department of Transportation.
Hidden Costs and Local Realities
Prices for Alamo car rental San Juan fluctuate wildly. In May, you might find a car for $45 a day. In February? You might be looking at $120.

Always check the "Airport Fee" and "Customer Facility Charge." These are standard across all airport rentals but can add a significant chunk to your bill. If you're staying for two weeks, it might actually be cheaper to take an Uber to a local neighborhood rental spot, but for a 4-day trip, the convenience of SJU pickup usually outweighs the cost.
Gas is sold by the liter in Puerto Rico, not the gallon.
1 gallon is roughly 3.78 liters.
Don't panic when you see "$.95" at the pump; it’s not the 1970s, it's just the metric system.
Finding the Alamo Lot at SJU
It can be confusing. You’ve grabbed your bags. You’re tired.
- Exit the baggage claim and follow the signs for "Rental Cars."
- You’ll cross the street into the multi-level parking garage.
- Alamo shares a desk space with National.
- If you used the "Skip the Counter" option, ignore the desk and follow the signs to the Alamo/National rows.
One tip: Check your car for existing scratches. The "island vibe" means sometimes the check-in process is relaxed, but you don't want to be blamed for a dent that was there since 2023. Take photos of the bumper and the rims. Always the rims.
Navigating Out of the Airport
Once you leave the Alamo lot, you are immediately dumped onto the Román Baldorioty de Castro Expressway (PR-26). It is chaotic. People merge without signaling. Speed limits are more like suggestions. Keep your GPS on. If you miss your exit for the Teodoro Moscoso Bridge (which is a toll bridge, by the way), you’ll end up in Carolina or headed toward the San Jose Lagoon.
If you're headed to Old San Juan, stay left. If you're headed to El Yunque, stay right.

Why Alamo Beats the Local "Budget" Brands
You will see ads for local companies like Charlie Cars or Allied. They are often cheaper. But here’s the trade-off: those lots are off-site. You have to wait for their specific shuttle. Sometimes the shuttle is full. Sometimes the shuttle just doesn't show up for 20 minutes. Alamo’s reliability and the fact that you can just walk to the car is worth the extra $15 a day for most travelers.
Also, Alamo’s loyalty program, "Alamo Insiders," is free. It gives you an automatic discount. There’s no reason not to join it before you book.
Practical Steps for Your San Juan Rental
Don't just wing it. To get the best out of Alamo car rental San Juan, follow this sequence:
- Book early: Prices in Puerto Rico rarely drop last minute. They almost always go up as the fleet gets reserved.
- Join Alamo Insiders: It’s a 5% discount for essentially zero effort.
- Download the offline map: Use Google Maps or Waze to download the map of Puerto Rico. Cell service can be spotty in the mountains of Cayey or near the rainforest, and you don't want to be lost without a signal.
- Inspect the Spare: Before you leave the lot, check if there is a spare tire or a repair kit. PR roads are brutal, and a flat tire is a real possibility.
- Check for the Transponder: Ensure the AutoExpreso tag is stuck to the windshield. If it's missing, you'll be stuck at toll booths with no way to pay.
- Verify your Insurance: Call your credit card company or your primary insurer to see if they cover Puerto Rico specifically. Get it in writing if you can.
When you return the car, give yourself extra time. The entrance to the rental return at SJU can be easy to miss. If you're coming from San Juan, stay in the right lane as you approach the airport and look for the "Rental Car Return" signs that lead into the parking garage. Fill up the gas tank at a station a few miles away from the airport; the ones right next to the entrance have a notorious "convenience markup." There is a Puma station on the way in that usually has fair prices.
The island is yours to explore once you have the keys. Just watch out for the iguanas on the road—they're bigger than they look.
