Definately can't use the inn return. It dumps my loot list about 10 secs after leaving the room every time. Best option: aetherite in town. Doesn't seem to affect loot list timer. Either way you're stuck waiting for your return timer afterwards.
I just prefer to make the rounds between camps (uldah > Nanawa > mun tuy > inn > repeat). And I also damage the gear so I can set it for repairs. I don't bother with the loot trick since using the inn prevents it. :(
