One aspect about being on site or travelling away from home is that the food is normally pretty good. Children like to hear about what was on offer and may even want to copy the menu and do it at home.
Why not give it a go? You can set up a menu (bring a copy of what is on offer back home or if you do not want to expose the fact that you get 7 flavours of ice-cream, write down an abridged version), then enact it for a meal. It does not have to be fancy and your kids will really enjoy sharing some of your experience. It is not the meal itself that is important – doing it together is a way of really bonding.
