Sorry, I haven't been accepted yet. I hope to go in Spring 2012, but I would like to know if you can request a check-in date because my current rental agreement ties me to my apartment until the end of January.
There tends to be a selection of days to choose. So when I went to accept my Fall advantage invitation I had 4 check in dates I could choose from. Depending on when you get accepted some of the dates my already be full. But you do have some choice in when you check in. When I did Spring 2010 there were check in dates into February. If that is the case again, you should be able to select something that will work around your apt situation.
