I would like to know if the pool is open? If so, do you have to make a reservation?

The pool is open to guests of the hotel as you need your room key to access it.

Only from 9 am to 9 pm

Was there a week ago and pool was open. Not sure about reservation. We didnt

Yes it's open...no reservation needed. Just your room key.

I don't know we just went for dinner there. You'd have to call the resort and find that out. Although I did see people swimming and sure that's for the people renting rooms at the resort. But you need to call.
