Hia Mrselliot, we recently got back from the Marhaba Club, the reps had quad biking on the form they give you if you want to go on any trips, but you had to be over 16, and the adult must hold a driving license, I know a couple of lads aged 16 and 17, went quad biking on there own, (booked it elsewere,) there was a guy selling tickets for quad biking by the beach of the Maraha Club, but I don't know how much he charged, my son (aged 14) would have loved to do the quad biking, but "my personal choice" I chose not to go with a sale of the ticket of a guy standing selling tickets for it.
Hope that helps
Roo
