Hi Ive just got back.
I don't think your boys will like the wave length club, my son is 10 and felt it was too young for him!
There is an arcade on both sides with pool tables, games, machines etc but you have to pay for everything.
In the evenings the entertainment is in the ampitheatre which starts for younger children really then at 9pm it's more of a family show. It's the entertainment team every night doing things like Las Vegas night and Queen night. If you've ever been to a Haven caravan park it's just the same. I have to admit we were fed up with it by our 2nd night! Some nights our children were both in clubs 9pm till 11pm but there was no where aldultish to go.
Every day there are lots of activities they will enjoy like archery, water polo, rounders, water walking, volleyball, gladiators, quiz etc.
There is parasailing on the beach £35 for 1 or £45 for 2. There is a banana and doughnuts. I think you can hire a boat there too to go over to the islands for better snorkelling.
Hope that helps, feel free to ask me anything else.
