Tinker, my point is that whether you’re on the dining plan or if your paying out of pocket, you need to make reservations in order to guarantee you’ll have a table when you want it and for the size of your party so you aren’t just walking up cold and hoping.
I don’t just hope. I make a plan, make reservations, and show up when my schedule says I should under all circumstances.
Besides, if you want to eat at the really popular places, you need to make your reservations as soon as possible. Places like le Cellier, Chef Mickey’s, California Grill, 'Ohana, Tusker House (breakfast), Crystal Palace book up very fast.
(And now that I’ve read the posts from Hanwill I see I didn’t really need to post this.)
