Shall we define three official categories?
1) Vacation/Holiday
Parts of at least two consecutive calendar days on WDW property, with at least one entry into one of the four major theme parks.
2) Grand Excursion
Part of merely one calendar day on WDW property, with at least one entry into one of the four major theme parks.
3) Excursion
Part of merely one calendar day on WDW property, with no entries into the four major theme parks.
Very nice... but if you eat at Boardwalk, we're you at Disney World?
