The DCs are keen to go back there but I think we'd rather go somewhere a bit more exotic/cultured!
TBH we'd prefer a city type break OR a less well frequented Mediterranean or Atlantic coast - we did enjoy an apartment with a pool on the North coast of Spain but I think they'd like the full water park experience. Plus they are old enough now to go in on their own so we can just read our books.
We enjoy walks and paddling on the beach but not just lying in the sun. I don't think either of them would be bothered about watersports, though DD and I had a lovely time kayaking recently.
They were also fans of the buffet though I think we'd go mad at an AI - I hate the idea of a Brits-only resort cut off from the world.
