I went to the Moon Palace on our honeymoon - it was seven years ago, but we loved it. My friends went a year ago and were very impressed too. Very nice resort and the pool is great. The hotel is down from the rest of the resorts and the sea isn't as blue there, but that didn't matter to us as we spent all of our time at the pool. From what I can remember the food was just average, but you're not going for the food probably!
I second the trip advisor site - take everything with a grain of salt of course but you'll get some great advice on the resorts. Good luck!
