BWVDee --
Why don't you just tie your dirty laundry to the back of the ship and drag it through the water...I'm sure it'll be nice and clean when you get to BWV.
especially if you do the parks, outlet shopping etc. or cook your meals in you room, it is really nice to be able to relax and be spoilt on the cruise at the end of your holiday.
We've done both cruise before parks and parks before cruise and definitely prefer to do parks first. We wear ourselves out from all of the park touring that the cruise is the ideal way to wind down.
Two years ago, we did a week at WDW and followed it up with a 7 day cruise. This year we are doing the opposite. Not sure yet which one I will like more.
