You can pretty much cross off a trip in January, I had an interview the 24th and the 28th. Feb is less of a problem, although HJD had a Feb 5th date (didn't go, too late for me, I was done). There aren't very many places that interview last week of Jan/First week of Feb, but there are some, and depending on how many places you want to interview, how solid you are, blah blah you might want to postpone your trip.
I found that when I was done with interviews, I still had a ton of work to do anyway, as far as filling out rank list, etc. and probably wouldn't have been able to leave even in Feb.
Just my thoughts......btw way, seems like you never get done with the chaos, now that school is done basically, and the match is over, this finding a house crap is just as bad
