February half term to Disneyland
Disneyland is wonderful, and easily exceeded our expectations, but we really should have budgeted more than one day for it. Central Paris also excellent - Eiffel Tower especially for children, but if you want to go to the very top, book online months in advance. We climbed on foot to the second floor, which was still pretty good, and you can just walk up and buy a ticket for that.
A piece of advice on travelling from CDG aeroport to the Disneyland station - there's a variety of options here, but we took the TGV from CDG direct to Disneyland (and back again on the way home). Takes literally about 10 minutes, and costs 17 euros for an adult. It's by far the most cost-effective and quickest option, especially since the TGV station is right next to the terminal for Easyjet flights. Follow the Grande Ligne signs.
