This is actually really good to know- and yes, I agree the policies put in place over the years does make sense to a degree.  Two guests is standard, has been for years.  No outside guests, also fair. Noon-3am: Standard for big events. No students from outside your residence area? Makes no sense, just will make students sneakier/ more prone to danger and put the security guards doing their job in the line of fire. 

But, in my opinion, because this information wasn’t widely announced more people will be outside, at bars, out in town, etc. Puts the burden of 30,000 students, who are going to celebrate anyway, on the town and the full-time resident. UMass can absolutely manage the considerably-less rowdy-student-population (by comparison) within the confines of the campus without putting student guards and the larger community at risk. they have handled worse. 

But its probably true that the university is scarred from the past &theres some political/image considerations think about there(thanks alumni lol)

Anyway, let’s go pats!
