Apartment Warming Party Timing

[hartmans]

So, I'd like to host a party at my new place assuming I can find someone to help me shop for stuff. It would be nice to have people over. What weekend would work for people? I'm going to be busy May 21 and out of town June 6-10. I'm not sure what sorts of end of term things I need to avoid conflicting with or when people are around.
