Depends on what you like...some exhibitionists love the first floor in addition to the convenience in getting to the pool and getting out to grab a coke from the fridge, no need to walk up the stairs or take the lift, very resort and banyan tree like.
Some people have too much to cover and prefer unblock view, or needs special privacy to do private things in the open. lol
it's really personal liking.....but the first floor has bigger usable PES compared to the upper floors for pays lobar suites, due to the smaller air con ledge for the first floors...i must admit that
