We went to the campfire last year; it was just as Gary described it. I thought it was good fun for younger kids mine were 4 and 10 (older one was not to keen I think it was her parents showing her up by singing along). Although they both loved setting fire to their marshmallows.
We were staying at the VWL but nobody checked or asked if we were resort guests. I don't think they are to bothered since there are lots of things to spend your money on whilst there such as pony, hay and carriage rides not to mention to odd gift shop here and there.
If you go dont forget your insect repellent we got eaten alive even though we had put repellent on before we went think we needed a top up whilst there.
