I just plugged in tentative tour plans for Dec 26 to Jan 1 and it felt like wait times were extremely low even though the crowd levels are noted at 9 or 10 for each day and for most of the parks for each day. Something doesn't feel right. For example, wait times for Dec 31 @ HS shows 26min for M&MRR, 43min for TSM, 23 for SSD. Now granted, the planner has optimized, but that still feels like short waits for NYE when the park is at a level 9 for crowds.
I looked at Dec. 27 for Epcot - a crowd 10 level - and Test Track shows 35 min wait at 6:55pm. Does that make sense?
