Meal plans come with "swipes" and "dooley dollars". Freshmen can choose among the A, A+, K or K+ plans.
All of those offer unlimited "swipes", which are what is used at the DUC, and Woodruff and Clairmont (upperclass) dorms, and Canon Chapel.
The freshman plans also include "dooley dollars" that can be used everywhere else on campus. If you use them all up, you can switch to real dollars. If you don't use them all up, they are forfeit at the end of the school year.
