Help! Best room rates for April 2006?

[rbalcom]

I really need some great advice on how I can get the best rates on rooms for a family reunion trip for April 2006. We have 13 in our group and the room tastes are as varied as the number of people. Unfortunately, not all of the budgets match. Right now the best I can do is 5 rooms for 10 days at the Value resorts.(approx. $5500 US) I'm hoping for a Canadian deal in the fall, but does anyone have tips or suggestions on how to do better than this.
