I'm thinking of booking a surprise trip for dd and her boyfriend as she finishes her A' Levels tomorrow. I've got some online quotes (from the Disneyland Paris official site) which seem pretty steep - we're in 'middle' season at the moment it seems, and just about to enter 'high'. Either way, the prices aren't hugely different. It will have to be onsite and we will need transport by Eurostar. Any tips?
