I actually went earlier last month and had the tour. The price was $60/month in the Chicago suburbs for the Gold membership (which means you can use any Gold or lower-rated facility). I'm not sure what the membership/joiner fee was, because they were waiving it or reducing it for last month and I don't think I ever bothered asking what it normally was.
I would take them up on the tour and the 7-day guest pass and ask lots of questions.
I go to Lifetime. It can be very crowded around Christmas and in the summer..sometimes after work and on Saturday mornings. They tend to overcrowd the popular exercise classes. They also have a problem with high instructor turnover (and employee turnover). I do not know if you need child care but some locations have cut the hours of the child care center.
They have cracked down on the guest policy this summer due to the abuse though. Now there are spots at the pool on the weekend. Last year it was at capacity.
It is 59.95 / month for a gold membership.
Definitely do the 7 day trial.. they are starting to cut corners at some locations so while it is still one of the nicest gyms around, they have been losing some members. But it does depend on the location.
the sign up fee changes from month to month.. right now its zero. When I joined it was a lot (100+ dollars)
