The only way to have a relatively easy and pleasant experience is to get there before noon and buy your entrance ticket ahead of time [online].
I don't get the token thing. Every event I have been too here at Salt River Fields requires tokens to purchase 90% of the food and beverages on sight.
Sadly I showed up (ticket in hand) after 2pm. The line to get in for those who had not purchased tickets was LOOOOOOOOOOONG. We got in with no wait. When we got in to the event the lines to get the tokens was LONG and at many of the more popular food trucks lines were even LOOOOOOOOOOONGer.
Having arrived hungry and having tried over 50% of the Food Trucks there in the past, my strategy was to find one of the shortest lines and eat. I found a truck that was just serving ribs, fried chicken and smoked potato salad. Ate happily while friends waited. Good strategy is to split up, each get a couple of items from the selected truck and meet up to eat.
Why are people so leery about trucks with no line. To me they have offered many good surprises. Come one sheeple try something new! You can get kettle corn and twisted taters at any street fair.
