Many bigger clubs won't do that. Beware of life time memberships. No facility can guarantee it will be around forever. Research the club's reputation. Make sure the staff are certified instructors and trainers, and avoid clubs that change management every few months.
Proximity is paramount.
If the facility is more than 15 minutes from your home, and not on your way home from work, you won't use it. Choose surroundings you like. An exercise buff who enjoys meeting like-minded people will want a different club than someone wanting to take her kids to the pool on weekends. Determine whether the program of activities fits your schedule, and find out when childcare is available. As with any money decision, research your options carefully.
