You can't go wrong in the Cancun, Riveria Maya area. We go 1-2x year. Customer service is great at even the lower end resorts. We have a now 8 year old and she loves the kids clubs, it is her vacation away from us.

Xmas is very crowded, we always leave the Saturday just before the holiday, the prices are a lot lower that week. I think you probably won't get great deals. Watch for the 90 minute time share presentation that lasts 3 hours, many places but not all expect you do to this to get a great price on the trip.

Bottom line for us, we shop the deal rather than the location, all the locations and staff will be good. The variable on the places is if they have the same buffett every day or al la carte menu also name booze vs local brands. For a week, who cares.

Dreams was one of our favorites, very high end. But we also loved Sea Adventure (formerly Blue Bay), it was a 3 star, but the most kid friendly we have been to.
