Fairymum, I don't think that my kids miss out. We do take them abroad...granted it is in a tent but they still get the fun and exposure to other ways of life. They also go to museums (esp if free!) We take out a yearly membership of the NT and get a lot out of that. They get taken to the park, for meals out etc.
We are very fortunate that we can afford to do it, I know that lots are not. My kids don't get everything, we don't do the hotel holidays abroad, designer stuff, must have toys, but they are not deprived, we are lucky.
