Are travel clubs worthwhile? Recommendations?

[papergirl]

This summer I want to take my two older boys on a trip--possibly to Wisconsin, where the oldest has a jazz camp for a week.
We'll be spending 12-14 days on the road, and I'm trying to figure out how to get by as inexpensively as possible, so I'm wondering about those travel clubs where you pay a yearly fee and then receive discounts on hotels, etc.
Does anyone have experience with specific organizations? I'm looking into a few tonight, trying to get some ideas, but I really don't have any idea what features to be on the lookout for.
Basically, we will need nightly lodging...we may do meals on the cheap.
Any advice is much appreciated!
Best,
