Done Eurocamp, Mark Warner etc when kids were younger. Now 13(DS) & 14(DD) and we're looking for a 2 week resort holiday in Europe where there will be stuff for them to do, stuff for us all to do and the chance for us to relax!
Fairly relaxed about budget(ish) and location. Things we like - sea, surfing, tree trekking, waterparks, football, and ball sports.
Not that fussed about AI or luxury accommodation, just needs to be adequate. Preferably atlantic France, Spain or Portugal due to surfing, but will consider anywhere. Don't need wild nightlife, just a few bars and restaurants.
Tenerife, Costa Adeje? Lots of nice hotels from 3 to 5* or S/C if you like. Great restaurants and places for evening family entertainment. Our DC loved it at 13/14 (and older). Atlantic so waves (though for the best surf you might like Fuetaventura) Most importantly it has the best water park in Europe (Siam Park). Good climate as not as blistering hot in summer as the Med.
I live in Carvoeiro in the Algarve, maybe a resort like rocha Brava or Quinta do Paraiso would suit. They're both quite big with pools/tennis courts, walking distance to a beach. Or monte Carvoeiro or monte dourado which are smaller but walking distance of the village?
