What are you worried about then if you like your other options? Anyway, its probably a yield protect, LOCI would probably get you off the WL.
I had luck getting my scholarship offer increased by $15,000 by e-mailing the general admissions e-mail address for the school (I couldn't find the direct e-mail address for anyone in admissions.). I e-mailed them a nice letter which included the total amounts of the scholarship offers I had received at other schools and detailed several reasons why I wished to attend school X. At another school where I hadn't received a scholarship offer initially, I e-mailed the person who had sent me my admissions letter. This school ended up offering me a sizable scholarship.
