Is this the one that is also a First Choice Holiday Village? If so, I would say it would depend on how much your 11yo wants to join in with stuff. We went last year with an 11 and 13yo and there wasn't really that much TBH. Neither were interested in the kids clubs and there wasn't much else. we've done HVs elsewhere and they've been really good, but this one has a bit of a split personality with neither Be Live or First Choice really winning.
