I'll take a stab at this one. We normally arrive the Wednesday before and stay until the Sunday after Thanksgiving. Historically the Thursday and Friday before Thanksgiving are
MVMCP nights and there are somewhat lighter crowds at MK. Be at other parks on Saturday and Sunday though. We have found lighter crowds on that Tuesday as well but here's a good lesson. One year it rained almost all day on a Tuesday. We stuck it out and just enjoyed our day at MK. They postponed Wishes over and over but finally started the show at 1am. I really think there were about 20 people there to view it. Absolutely one of our favorite memories.
Now, they are cancelling Wishes. Let that sink in....
