Hi Doepsmc
We were at this hotel last August and it was brill, the food was ok but we did go to Naama some nights....My children are 15 & 11 so it was quite easy, the temp at night does chill down in the summer ..... 35 at midnight!
Doing the alternate night thing is good we did that, and we ate in our room, they do a great club sandwich..As for the snorkling buy your gear in Naama bay it is really cheap ( £6-8) but you must bartter hard!! The Hotel is on the Garden Reef one of the best dive site it gets full of divers every day.
A good tip is to ask reception for an extra key card then you can leave air-con on all day the room will be nice and chilled when you get back from a hard days sunbathing. Also buy your water by the box full in Naama bay, loads cheaper. If you need some ring the taxi guy at the gate and he will pick some up for you next time he goes in.
We have just booked to go to Taba Heights only because we want to go to Petra otherwise we would of gone back to Crowne Plaza with out a doubt!
Have a great time
Stuart
