My sweetie & I differentiate between vacations and trips. This quote:
I am not the type who wants to go back to the land; I am the type who wants to go back to the hotel. -- Fran Leibowitz
demonstrates the difference pretty well, too. Vacations are restful, relaxing, and rejuvenating. Their purpose is to do very little and to do things slowly, soaking them up. Trips, on the other hand, may be thoroughly exhausting, full of activity, but also packed with great memories. Disney World is a TRIP. Soaking up sun in the tropics? VACATION!
