We have stayed at WVL a few times, most recently in September 07 and we LOVE it!!! Such a great resort with wonderful atmosphere.
One thing we found on our last stay, there is now a DIRECT bus from WL to MK!!!

You do not stop at any other resorts and from pick up to drop off the trip is about 5 minutes! Also, from the villas, the bus stop is much closer then the boat dock. It is a bit of a walk to the boat dock, but not too bad, and the boats can be a lot of fun! Keep in mind that they are "open" and can get a little hot and humid while the buses are usually air conditioned quite comfortably.
So for us with our 2 & 4 year olds at the time, we took the bus for convenience and the boats for experience. We also used the boats to head to the Contemporary so we could eat at Chef Mickey's and ride the monorail. This boat makes a loop of Bay Lake, so you head to the WL campground, too. They seem to switch up the routes, though, because sometimes we would go to the campground and then the contemporary and sometimes it was the other way around

no idea why.
Have a great trip! Jennie
PS - We love OKW, too, for the size of the rooms and the laid back feel of the resort, I think you will be happy at either place! We own at BCV but have not stayed there yet, waiting for the kids to get a bit older to enjoy the pool!
