Should I apply to more than one program?

Hi all-

I'm planning to apply to the University of South Carolina's MLIS program for the spring. I've been out of school for 17 years, so I really like the fact that they only ask for 2 letters of recommendation. Other schools I've checked require 3. It was hard enough to find 2 work supervisors who can vouch for me considering I've worked for the same boss for 8 years.

USC would also allow me to pay in-state tuition which is a definite plus. Although no one can "guarantee" I'll get in, does anyone have an idea how selective that program is? I had a 3.10 GPA and my MAT score is in the 99th percentile.

I'm just deciding whether I need to hunt down someone else to write me a letter.
