Well we did anyway. It was peeing it down all day. We had fun in all the roomsets, pretending to be a different family in each. DS's are 3 and 8. They loved it, it was hilarious, DS's could not stop laughing eg: 3yo made cakes with worms whilst 8yo sat at a kitchen table and they read the catalogue in bed under a duvet singing in another.
Meatballs and chips for lunch all round - A CHEAP FUN AFTERNOON OUT!!!
Try it.
