I choose Princeton Club over other 24 hour facilities for a few reasons:
1. Lap Swimming Pool open 24 hours
2. Warm Water Resistance Pool open 24 hours
3. Water Aerobics (they usually have 2-3 classes a day)
4. Almost all classes (besides cross training groups) are included in your membership
If I didn't want (and LOVE) the above amenities I would have gone with an Anytime Fitness closer to where I live.
My suggestions for the Princeton Club would be to keep the facility cleaner, have stricter cell phone polices (no one needs their cell phone in the pool area), and have friendlier staff at the check in desk.
