Even though I'm not doing it this summer, I still feel that offering helpful info is my responsibility. Nothing worse than a bunch of rude awakenings when trying to be on a vacation to relax and enjoy! I'd much rather people had the chance to learn what they can before traveling for days to get here only to find that everyone else on the planet had the same idea at the same time.
Funny anecdote from last July 4th... some guys from India were at the info desk inquiring about their plans in the park and there were tons of people in line. When they finally got to me they asked why there were so many people. I told them that it's our national Independence Day holiday so everyone is on vacation... and they all came here.
They saw the humor in it and we had a good chuckle, except that I was faking it.
The volume of people I had to attend to (mostly as travel agent and concierge) traumatized me such that I spent the first six weeks after my tour of duty ended in the house avoiding everyone, even my close friends.
