I am sorry but I totally agree with the Marriott and some other posters here - their policy is totally acceptable. I go to the Marriott because there are NO children and appreciate so much that they provide this restriction. the amenities for children are for guests only and it is well located between beach and pool so as not to disrupt relaxation. I love swimming and other clubs have no beach and too many sprouts cluttering up the pool and sqwaking you can't relax or have a decent swim. I am surprised you slagged them off as being dirty, having been a member for three years I find the staff great and enjoy the facility. As the hygiene standards don't meet yours then really the restriction is a secondary factor.
