jjohnson's list is really great! It's nice to know what is available, but I want to offer a word of caution. In the past I spent WAY too much time trying to figure out the "best" way to use my snack credits that I ended up paying for some things with cash (like a bottle of water) and then having credits left over. It took me TWO trips to figure out that I was being a dope

. Since then I just use the snack credits as I go along when I am hungry or thirsty. It worked out much better for me with less OOP expenses and no left-over credits to use or lose on my last day.
