We had a studio too, you park the car in the underground car park and you should be in the main building so it's just a lift up to your floor. The girls (well remembered, 6 & 9) did a number of clubs but tie die T-shirt and shark tooth necklaces were their favourites. The kids club people get them doing dancing by the ppol and a quiz for sweets that grown ups "help" with was good too, mine are pretty shy but they joined in pretty much everything. I'd say the interaction with kids was as good if not better than on the cruises if you've been on one!
The pool is heated even in summer so it's absolutely glorious to be in from am until after dark for kids and grown ups alike and I can tell you I went down the slide as much as the girls did, it's so fast.
We also did the camp fire which I mentioned, we're a pretty quiet reserved family but were all singing along at the top of our voices with the kids, the girls still break out into some of the songs now nearly a year later. We also did an astronomy night where they got a big reflector telescope out on the deck after dark and the girls could see the moon and a plant (mars I think). Only about 10 kids showed up to give you an idea how cosy it all felt. To wile away the time waiting for the sky to go dark, one of the club people brought out loads of bubble mixture and wands and they all ran around like loonies blowing giant bubbles on the deck.
Finally, I was nervous of no-see-ums but I needn't have been. None of us set foot on the sand, we were having too much fun at the hotel!
