I've run into a problem. I'm arranging the family vacation to England & France next year. We are planning on spending a single night in Bordeaux. The problem is, the night we want to stay there coincides with the start of VinExpo!

Questions:
1. During VinExpo, how full is the city? Would it be best for us to avoid the area during VinExpo?
2. Will the neighboring Chateau be more or less open for visitors during the show?
3. Any suggestions on finding a hotel in the area?

Thanks for any help or pointers!
