You all bring up some great points.  Many of which I'd already considered.  The one time use rule was something I did not know (and a bit of a bummer) but can be resolved.
Just to clarify, I am not planning on ONLY traveling over Thanksgiving.  We happen to like to go that week, but every other year or every 3rd year is more realistic. 
Mid-December thru Christmas Eve is very do-able for us right now.
Also, NYE thru mid-January work well.
DH and I can be very flexible.  A HS and college kid...not so flexible right now.  That may change.
We have no desire to be in Florida June - August.  Never will.  Made that mistake last year.  Not going to repeat!
We don't really care where we stay.  I can't think of 1 
DVC resort that we would say "No thanks" to.  However, unless we absolutely fall in love with 1 particular resort, we would like to not have to stay in the same resort every. single. time.
We can stay 4 nights, 5 nights, 6 nights.... It's all good.  I get that we can stay less nights at some resorts.  Also, my DH and I may come earlier / stay later than the kids sometimes.  So, 1 studio for 6 nights, 1 studio for 4 nights.   Especially as they get older.  We can make our points work.
What is not optional is that we want 2 studios.  So, does this mean DVC is not going to be right for us?  Or is this just really a concern at BWV over Thanksgiving?
