Thank you all for your replies. It has given me alot to consider. We would definitely stay at VB at times, as we love the beach. We would almost ALWAYS be booking late September through mid-December, but never over holidays. We like those "dead" days at the parks.
I think we will keep our eyes open for other deals for now. We would like to be able to stay a week or so at AKV or BLT, and next year at the THV at SS at the request of our son. We did do some tours of some resorts last week...love AKV, sort of liked WL, not incredibly impressed with SS, love BLT. SO much to consider, though. We almost always drive but that doesn't mean we won't fly one of these days.
Thanks again for the input, everyone!
