@skd33 - "The Unofficial Guide" Crowd Calendar rates crowd levels at WDW on a scale of 1 (low) to 10 (insane). Their predicted crowd-level ratings for that week in January 2012 are as follows: Jan. 1: 10, Jan. 2: 9, Jan. 3: 2, Jan. 4: 2, Jan. 5: 4, Jan. 6: 4, Jan. 7: 3, Jan. 8: 4. By way of comparison, the predicted levels for next week (i.e. March Break 2011) are Mar. 12: 9, Mar. 13: 9, Mar. 14: 10, Mar. 15: 10, Mar. 16: 10, Mar. 17: 9, Mar. 18: 9, Mar. 19: 10. Of course on the flip side, the weather in March is nicer, but I would rather avoid the crowds...
@Tower - not sure about other years, but the 2011-12 Christmas holiday dates for the Ottawa Board are actually different than the dates recommended by Ontario Ministry of Education (which are Dec. 19 to 30). But I believe each individual school board can choose their own dates, but they have to be approved by the Ministry. So I guess at this point the Ottawa dates are still "provisional" until formally approved, which should happen sometime in the next few months.
