cait, I am also in the same boat -- I cannot decide. I find one resort I like and then read a little about it and get discouraged.
As for pricing, I'm just using Expedia to check what the Aug/Sep 2009 prices are and figuring it will be a little more than that next summer. i'm trying to keep the 8d/7n price to $1000 or less.
Resorts I've considered:
Iberostar tucan/quetzal
riu palace las americas
riu palace mayan riv
barcelo maya palace
I think my first choice is now the barcelo maya palace. I'm waiting to hear back from the WC on a few questions I have (and also waiting for the 2010 wedding packages, I only have 2008/2009). The good thing about the barcelo maya palace is that it's relatively new, affordable, and they have a beautiful beach. Oh and big plus is that if you stay at the barcelo maya palace, you get to drink 'premium' alcohol which is a good thing for my family of lushes..haha
Good luck with your search!
