Teen clubs are for meeting others to hang out with. My 5 are very close in age and close to each other, yet always found their own groups of friends on cruises, on the last one dd14 had a group, ds14 had a group, dd16 had a group, ds19 and dd20 shared a group (more difficult without a club). He won’t be hanging around with 12 year olds, they sort themselves out.
