We have a courtesy hold on a 3-night cruise on the Disney Wonder in Oct 08. I think we'll be putting a solid booking through in the next few days.
It will be 5 of us -- DH, DD 10, DS 7, DD 3, & Me, or 6 of us if Mom comes, too.

Either way, we have 2 adjoining oceanview staterooms.
Our kids have NO idea. They don't know we're planning a trip to WDW, they know nothing about us considering a cruise, and all along we've told them that if we went to FL we'd be driving. But hubby and I have decided that by the time we rented a car (don't want to use our own), paid for gas, and at least one hotel room along the way (driving from CT), we haven't saved that much money. Not to mention time, which is more critical when we're pulling the kids out of school...
Anyway, hubby and I are very excited and will be looking for creative ideas from this board on ways to tell our kids about our trip, when the time comes!
