For the all-inclusive: do you have to do it all 7 nights, or can you do 4/5?

Yes, you can do as few as 4 nights, but not the "middle days", it must be the front or the back end of your trip. Note you don't get the member's discount on the AI, unless they are on the reservation and in the same suite as you. You will pay the 'rack rate' for this. It's great food and drinks, though, I must admit.

Thanks! I stayed once, years ago, before all inclusive. I LOVED it. It’s one of the few places I’ve gone where I felt I could stay forever.
