Yeah, the snack bar is just by the pool, which means parents can get on with the important activity of drinking while their little dears have fun in the water. You can get beer, wine, coffee, juice, crisps, pizzas, chicken nuggets, chips, omelette, ice cream - all that kind of stuff.
I also seem to remember that the year we were there, the nannies helpfully ran a film club one night a week. You paid a fiver I think, and the kids were taken off to watch a couple of Disney videos and eat popcorn, while the parents went out to dinner.
Another good thing to do is to take the boat trip which you can buy tickets for in the local supermarket. It's a speedboat rather than one of those huge galleon type things, and you get to visit various coves etc, swim in quiet waters and go turtle spotting. Don't take your kids unless they're older though, otherwise you'll spend all your time trying to ensure that they don't fall out the boat.
