Big Brother 18 is a week away, but first... we got a tour of the new house!

Host Julie Chen took us around the revamped abode, which boasts a summer vacation/travel theme this year, perhaps taking a page from The Amazing Race? Each room represents a vacation destination. There's the African safari room, the demure London bedroom, the funky Japanese anime chamber and a beautiful faux mountainside in the backyard. See, it's just like you're in the Rockies!
