50% of our time was outside of the hotel, but the days we decided to relax I wish I was smart enough to tip in advance for a cabana. Out of the 5 days we stayed by the pool we got a cabana one afternoon only.
I tipped the guys at the bar by the pool and one of the guys that helped us with towels/sun beds the night before we left. Probably should have done this the first evening!
Anyway, it should be noted each evening my wife and I took a walk on the beach and went to our room by the club pool . The 2 cabanas on the grass between the pool and beach seems to be the night time bed for a number of feral dogs.
