Drinks at AI are not very strong.... You will have to ingest a lot of liquid to get a buzz..
I agree with that. I have not stayed at that one but most of them the drinks are not that great. If your friends like a premium alcohol besides rum they might want to buy it in duty free and bring it. Not sure I would trust they are going to give you a good amount of quality vodka, bourbon, etc. Even the rum would probably not be the higher quality. Also they also seem to only serve presidente on draft. It is a decent beer but only when it is still cold and it would be nice to have a variety. Or if they want a good bottle of wine or champagne.
Not sure about there but most of them you have to make reservations for the restaurants soon or they will be full and you will be at the buffet. If it is the type where you can just show up the the restaurant that is a lot better.
Bringing a better drinking cup is not a bad ideas something that is larger then the little plastic cups most of them give you and might keep you drink colder.
Looking online iberostar doesn't seem to let you book for one or two nights. I see a three night minimum unless I am doing something wrong. Maybe they are trying to keep the locals from going there one or two nights. The price I see for two people is $152 a night.
Let me know what you think of the place. Here I have stayed at Barecelo, Blue Bay and Lifestyles.
