We are staying about an hour and a half max away and have got 20% off vouchers on adult tickets. I think it might be husbands idea of hell as he can't seem to do crowds. However, me and the boys (11 and 17) have done the olympic park yesterday and other type attractions. I'm just wondering if it is worth doing or not, particularly for my youngest. I was toying with the idea of leaving husband back on the campsite as it's more stressful having to deal with him being grumpy but it means then that the driving etc is all down to me.
