With packies, you can make them stand outside the house, while you're inside. All follow me on macro, and you can grab that chest you have your eye on while your packies are walking to you.
Or you can have the summon familiar spell on macro and summon minion as the house falls, although you may waste a couple of seconds clicking the horde minion button when the gump comes up
Anyways, better safe than sorry...I've gotten stuck and had to re-log, etc during an idoc before as well, I'm assuming because I had my packies inside the public house with me (evidence suggests, anyways).
