Can you use the resort pool if not staying at the resort and just doing a day trip to the island?
No its for resort guests only and sometimes there is a resort staff member making sure no one sneaks past
i don't know
You can do a day trip out to the island but you can not use the pool.
The pool is for resort guests only and you will be given a wrist band if you do a day tour to the island so the staff will not let you in the pool. However, if it's nice weather, the water is way better than the pool anyway so I would suggest to just go for a swim in the water off the island
