You pay for the cabin, rather than per person. I was so impressed with the cabins, don't know what i was expecting, but it certainly exceeded it.
There's a little village of shops, bars, restaurants and coffee shops with a little supermarket. I must say I was actually pretty impressed with the supermarket, I was expecting over-priced happy shopper, but it was really good quality, and not too expensive either.
I'd always been put off as i thought it was really expensive, but it's only the more 'extreme' activities which are pricier, plus there's loads of free things to do. I faced my fear of being seen in a swimming costume, and then i didn't want to leave the pool- and there were an awful lot of very big people in there, so it's not like it was full of super-skinny's.
