I'm rubbish at booking holidays. I know what we'd like / need but tend to get bored before I've found it 
'We' are DH, 2 DCs and me. The DCs are young adults so don't require any kids clubs and we would all like sports/gym, swimming (sea or pool), water sports, trips, walking/ exploring, good food, ideally option to self cater lunches.
Any suggestions gratefully received.
TIA
