A Big Mistake
IMHO is the average traveller doing the AI thing all the time is totally missing all the adventrue and the fun of a small local hotel, eating in the various eateries and buying drinks etc., at a colmado and going to the beach and beach bars.
All this staying with your neighbors essentially in a walled compund means you haven't "travelled" at all other than to a place where the wages ar so low they can package food and booze for next to nothing inside a prison.
Any AI could be in any of Mexico, Central America, the DR, Cuba, for all it matters to the tourist and the experience is always the same.
I am not even convinced anymore that you save money since you can use the airfare part of the same AI charter trip to save money over say, AA, and then live on your own for no more than the hotel / meal part costs.
And going out on a "safari truck" or "catamaran to Sanoa" etc., with a gaggle of fellow caucasians, is not going into the country as much as it is keeping you protected forom the actual country.
Bah humbug to these resorts.
