But I can't decide if I want to go or not. I normally go with my mum and last year we spent the night in London as well (which was actually terrible as I had yet another vomiting bug which ruined the whole thing). I trying to decide if we should do it again, or spend the money on something else. When you add it up with tickets, train travel and accommodation, it costs about £300 for the two of us. It is worth it?
