Only been to DO III.

Friday party getting buzzed by some 747-F.

Getting to use a overwing exit, plug style.

Getting to put on a life vest and inflating it.

Seeing more noise cancelling headphones that were left on board in the past month than any Best Buy keeps on stock.

About the classy part of the Saturday, I remember at one time walking down the stairs from the upper level of the PC and the music was just perfect for walking down the stairs in a suit. The stairs were also perfect for that too.
