Just pulled the trigger on Nov 15th - 19th. What can I expect as far as crowds , ride closures ( already know about Small World ) , Christmas lights etc...
Birthday presents for me! Oh wait, I guess you meant for your trip LOL
It starts off on a weekend so you'll have the weekend crowds, but you are between Veteran's Day and Thanksgiving Day, so you should be good there. We went last year at this time (for my birthday!) and the crowds weren't bad for those days. Just take advantage of FP's, MM (if you get them), and park hopping and you should be good to go!
Congrats on making the trip official. Feels good, doesn't it? The crowds should be very low (except for Sat) and the decorations up! Have fun planning and have a great trip.
