Okay, as a frequent traveler from Hawaii, I am obligated to say that terminal 2 sucks bad. My recent trip back to my second home, I traveled from Vegas to San Francisco in the main terminal, which was SO AWESOME!!!
The gathering areas were huge, the food places were clean, and the concessions were decently priced ($6 bud light is ugh). Free Wi-fi tops it off as the best airport experiences, I've ever had.
