Up here in the northeast we have vacations in February and April (I don't know if the rest of the country does as well.) I know a lot of families take trips to WDW during those weeks. April break for Connecticut and NY is the 9-13. April 16-20 is Maine, Mass and Rhode Island's spring break and New Hampshire is off April 23-27. Vermont schools are closed either 16-20 or 23-27 depnding on the area. So I'm sure those weeks will be a bit more crowded than the last week when I don't think anyone has any vacations.
