2007: We’re banking as much of this year’s vacation time as possible to save up for next year.
2008: 15-night Disney Cruise, aboard the Magic, repositioning from Florida to Los Angeles via the Panama Canal.
2009: Very likely a group WDW trip with friends who have been waiting for their youngest to be old enough to enjoy it.
2010: Vancouver for the Winter Olympics.

For 2011, we’re considering either Japan or Europe. We had to get our passports for the Disney Cruise next year (and I’m still waiting for mine, 15 weeks into the 10-12 week estimated return) so we’ll have them if we do want to go international.
