The trip schecduled for Mexico during spring break has been cancelled due to the bankruptcy of the bus company. You must tell 25 of your classmates that the trip has been cancelled and that they have lost their $100 deposit. How will you convey the information and still uphold their goodwill toward you?

My problem is trying to figure out how to address them in a memo form without using their names or the name of the school, neither of which I know. Any suggestions?

How about --

Dear Travelers,

or

Dear Friends,
