I love WDW in November but the weekend of Thanksgiving you're definitely going to have to prepare for some crowds.
There's a lot going on over in Fantasyland right now. Pooh's Spot is closed. The Pooh ride is closed for refurb. The Mad Tea Party should be reopen by the time you go though.
Star Tours at DHS is closed.
Other than that you shouldn't have any closures (other than those due to an issue that are unplanned etc.).
The temps are awesome this time of year. Look for highs in the low 80's and lows in the high 50s.
