Cabo Azul is not an all inclusive hotel so just like any regular hotel anyone can go to their bars and restaurants. We like the happy hour at their pool bar where you can also purchase food, but only guests are allowed to go into the pool and use the loungers around the pool.
Doh! so you can't pay for daily pool access? :(
Not that I am aware. Other all inclusive hotels offer this option for a fee. For example, Barcelo offers a day rate (something like $75 for 9:00 to 5:00) and an evening rate for 5:00 to midnight. You can check at their front desk for details.
