do all AIs provide poolside towels ar do you BYO to be on the safe side?

AI's, as well as most any of the hotels in the Caribbean, always provide beach towels

I always take 2 anyhow. Sometimes they are out or if you go on a day trip they want their towels back by a certain time or you get charged an arm and a leg for them. Sometimes the trips aren't back in time.

thanks, it seemed a silly question but we have e-mailed our hotel with that question and we have had no reply. Hopefully that is not an indication of the standard of service we'll get when we are there!

One more thing I did...we went down to the islands for about 4 weeks last year and I took OLD beach towels and when we got to our last stop I just left them there. That gave me room for all the goodies I bought while I was gone. I know people that do this with underwear and everything. Take old and when it's dirty they toss it and leave room for new stuff.
