No missed connections is good, and so is finding something decent to eat at the airport. But really, my idea of fun isn't just the absence of negatives. For example, I love it when they have interesting exhibits in airports. In Atlanta I enjoyed an exhibit of puppets from around the world, especially Petruk and Gareng, two clowns from Java.
The best part of traveling, however, is arriving. Seeing friends again. Hearing parrots flying over the house in the morning. Eating breakfast including local coffee on the balcony and being warm. Pura vida.
