Well you're still lucky to be during week 2-9 because there is even less availability for March 10-22!

Didn't see that package before, cool to include both cards for the price of one!

You could also try to book directly wth the hotels suggested by this site and see if it's cheaper booking directly with them.

You could try calling the Days Inn also, there will be a bus of people from my school that week, I guess it will party pretty hard lol
