I also agree that crowds are likely to be on the high side through the 10th. The AP blockouts end the weekend before (1/3 and 1/4) so this will the first/last chance for the local AP holders to return to the parks and experience the rides closing on the 11th for potentially a year or more (Rivers of America (Mark Twain/Columbia, Tom Sawyers Island, Canoes), Big Thunder Ranch and BBQ, the railroad, Fantasmic!, and Aladdin), along with those that are closing to have the seasonal overlays removed (HMH and Jingle Cruise) and other refurbishments (Autopia and GRR). Also, as mentioned, some of the local school districts (e.g., LAUSD, Orange, and San Bernardino) are still on winter break through the 10th. So, I would expect to see crowds remain fairly high through the 10th. There might be a slight drop on the 7th (Thu), but I expect the crowds to return on the weekend.
