We split our stay up this past January. We were going to be arriving on January 1st and I decided we should be at Disney for NYE. So I booked one night at VWL and then we moved to BWV. It was a bit of a hassle. We hadn't really unpacked alot of our clothing but I really needed more time to take advantage of all that the WL had to offer. If you are splitting your trip up somewhere in the middle it would probably be okay. I found it hard to leave WL after the one night. I'm assuming you are bringing your own transportation. We ended up renting a cab and that cost us about $20 w/ tip. You have a much smaller distance to travel but it looks like you have a larger family, so a cab might be a little pricy. I think you can also take ME to transfer from one resort to another, but you may need to make reservations to do that, not quite sure. In any event, you are staying on Disney property and that makes the trip so much more. I love being surrounded by Disney during my entire trip. Have a great vacation!
