i belong to lifetime and love it! funny to hear about thongs in the pool- never saw that before. yeah you see sports bras in the gym when working out but big deal. do whatever is comfortable for you.
i usually work out at the one in bloomingdale or schaumburg but also visited the one in algonquin numerous times. it can get crowded- especially for the new years resolutioners, but that dies down mid-late feb or for sure in march. the pools are nice and the equipment is great quality. all classes are included and they can get busy but just get their early to get a spot in the class.
the child center is great for kids. i have a 3 year old and have been going when he was 15 months. it is big and a lot to do. if you don't feel comfortable with your little one wandering all around, they can keep them only in the smaller kid area. they have computers for bigger kids, a whole climbing area, bbal court, infant area, enclosed play area.
it is kind of pricey, but it's more than your typical club. the food there is good and they also have a spa on site. the locker rooms are nice and roomy- can get busy at peak hours (5-8pm mon-thur). i just try and go at odd hours and have no issues- it's nice how they're open 24 hours. child care center is open around 9-9; weekends a little shorter hours.
staff has been great. i recommend taking advantage of meeting with a trainer. all of them i've run across have been very nice and professional.
good luck!
