None are good unless your Disney vacation will have three or fewer days in the theme parks.
For longer vacations the timeshare prize tickets give miniscule savings off of your ticket budget.
I have been to Orange Lake Country Club and also to some that are no longer selling and therefore no longer offering promotions. You need to be "thick skinned" and be able to say "no". Also to be able to break in and admonish if the sales agent gets rude.
