One night of discount on a hotel will usually "pay" for the $12 year membership. I had let mine lapse ( joined at 50 lapsed at 51) and when a hotel I was booking in Texas for 4 nights had an $11 per night lower AARP rate, I reupped. Note: My husband is 3 yrs younger than me and is a complimentary member because I am. ( He wasn't thrilled with being a senior before his time, but ? :D Since he has to hang around with an old lady, might as well get the benefits!
