Yes, you can buy water at the distributor. You can also buy coke lite, sodas and beer. They are located about 1/4 mile south of the airport, open Monday thru Sat.,they close for lunch between 12:00&1:00. Just have your taxi driver stop on the way to your hotel. Please give Roberto(works at the distributor) a message for me, that I'm working on his DVD list,and will be back first week of April.
Thank you Kathy
