Anonymous Yalies railed against the "invasions of crowds from such lowbrow places as the Bronx" in a Monday New York Post article. Mrs. Harrison DeSilver (according to New York Magazine's Daily Intel, this is the name of an architecture firm upstate and not a well-chosen pseudonym) says:

I just want to put my feet up here, but instead, weddings are being shipped down from The Bronx

The article contains more grousing about the Bronx as well as descriptions of the Yale Club's exclusive accommodations (beds! a gym! a place to eat! a basement dungeon!). Daily Intel's analysis of the article suggests that disgruntled club members are actually upset about sharing facilities with the UVA Club and the Dartmouth Club and not the occasional plebeian wedding. Daily Intel says:

The tabloid cries snobbery! Except they've got it all WRONG. It makes the Yale Club sound racist or something, because presumably they're not talking about all of the Yale alumni up in Riverdale. But total strangers can only usually use the club when there are weddings or other major events. They're not the ones in the swimming pool or at the gym. No, club members are annoyed by a different kind of crowd — non-Yalies who get in with reciprocal agreements from Dartmouth and UVA. Elis don't have a snobby Bronx problem, they have a perfectly understandable safety-school problem.

Are Yalies upset about sharing their facilities with Dartmouth and UVA grads? Maybe. But in the Post article they're mostly upset about "weddings being shipped down," "the practice of renting out rooms to the public," and outsiders staying overnight and using up all the space.
