This might be a bit of a random question but has anyone tried to book a short break at warwick castle/alton towers/Chessington recently? I've been looking at all these places for half term for 2 adults and 2 children. Every time I get through to the 'add a second day' option it is defaulted to 3 adults and 1 child. I am able to make it down to 2 adults but it won't let me add another child to make it 2 children. This happens on all of the above sites. It's driving me mad! Does this happen to anyone else? Anyone managed to get round it?!
