My spouse has just declared that our next trip will be to DLP. I have no idea how to plan this. We'd be coming from the US, and would likely only spend an extra day or two outside of the park. Any good 'getting started' resources? For example, if I could figure out a cost I could decide if we should try to go this Christmas or wait until next fall or even Spring of 2016... 

just leave the country of your address as Belgium/France etc. All correspondence is sent via email so it's absolutely fine to make a booking this way.
