I had one, and it was GREAT! The port (at least in my apt. @ Chatham) is in one small corner of the living room by a table, so even though there were 4 connections, really only one or two people could be on at once (and there were 8 of us!) It's not necessary, but you'll probably want it. You can always wait until you get there, though, to see if someone else brought one or if anyone wants to split the cost with you.
