The word "vacation" brings many thoughts to mind:
The mad scramble to call shotgun, which gives the victor power over the music player and the air conditioning, as well as a lovely view while not having to sit next to a sibling.
Calling "Dibs!" before the others in the hotel room at midnight, claiming dominion over the bed closest to the A/C and the view of the busy nightlife outside.
Then the exhaustion after only the first day of vacation, winding every person to a bit of a temper and mood.
I don't know about you, but my "Vacation" definition is usually "more than two days out of the house". That is the only requirement. It doesn't seem to matter where my vacation venue is, whether it's a trip to grandma's house for Thanksgiving, a weekend working at a homeschool convention, or even a sleepover at a friends house. Anything that takes me out of my normal routine is a vacation in my mind.
As for my friends, the beach is a popular vacation spot, along with Disneyland, DisneyWorld, New York, and Hawaii. But with those vacation spots comes rigorous planning and scheduling, packing everything you might possibly need, and preparing several months in advance.
Now, I'm not saying these aren't bad vacation spots. They're great. I'm not saying that I am not a packrat who always takes more than I'll ever need "just in case". I am.
