We have never used the long term parking. We have our driver take us there and pick us up. Or we park off the air port and walk the three blocks. If you like I can drive you there and pick you up it no cost, either your car or mine. I would be glad to do that for you. My method is safe for you and your car. This offer is good 24-7-365.
Parked there several times, once for 3 nights with no problems. Just inform the guards that you will be staying overnight and they will record your plate... 150 peso fee per night
Thought it was 200 per-night when we parked there a few months ago for several nights. I remember thinking that it was pricier than I expected. But it certainly could have been 150. And do tell the guard at the front gate / entrance.
Why would you think 4 bucks a night is expensive if the car is parked overnight and you get back the next day undamaged? Seems to me to be a good deal.
Yes, can confirm it's currently P150 per night. When I first did it they gave me a form for the car's details which I scanned and just print each time to give to them. I've used it several times over the last year, twice for 6 nights, and had absolutely no problems.
