A variation on a timeshare.

Look carefully at the economics:

Figure *ALL* the upkeep costs. You're getting close to the price of the rooms. By the time you add in what you could make on the money you have to pay for the membership it's normally a bad deal.

Also:

You're a captive audience. What incentive do they have to keep things up or keep the maintenance fees reasonable?

Also:

Look at the resale value of timeshares. About $0.

Also:

Look at what their promotion is costing them. That has to come out of the sales price.
