So Planet Fitness (gym) is offering free summer memberships for teens ages 15-18. We actually have a new PF that is very close to my house. This would be great for my daughter. However, in looking at general reviews of PF,there are complaints of PF continuing to bill credit cards after people stopped their memberships, etc. I don't know what is required for the free teen summer offer, but I am guessing they will ask for a credit card and have some reason why this is necessary.

Any thoughts or experience with this?
