If you wanna be there when it opens, be there the second weekend in March. That is when Spring Break starts. ASU, U of A, USC, many other schools will be there March 16. If you don't believe me, (I know you guys like picking on the bull) check out there websites.
www.asu.edu, www.usc.edu., www. UniversityofArizona.edu. And look under there calender. I was there last year and let me tell you when ASU and U of A get together it turns into a crazy ass party.
