Because I also teach, we typically go President's week. I don't find the crowds unmanageable. With planning, fast passes, and using the early and late magic hours, our trip was always enjoyable. This past year we went the last week in June instead and found the parks extremely crowded, worse than our February trips. Living in the northeast my only concern with February travel...snowstorms and airfare cost!!! Have fun planning your trip, go with an open mind, and enjoy yourself!!!
