I went at that time last year & DH went at that time the year before (I was 8 1/2 mths pregnant so couldn't go). We were very lucky with the weather - only needed our fleeces instead of coats. The queues with very short (but we were mostly doing kiddy rides) & there were fireworks on some of the nights because they celebrate bonfire nights that week. I really really wanted to go that week this year, but DH couldn't get off work so we are going in October instead. As the week goes on the Christmas decorations keep appearing overnight. I think it is a great week to go.
