a trick I learned on this board is this:
When you press the globe for the map, in the lower right hand corner is a check box "Advanced Mode". Click on this checkbox.
Now, when you click on a room to enter it, you will receive a list of rooms that are open. Actually, they are called instances. They are labeled with directions, such as "north" "south" "north-north-west" etc. Choose one with either no mickey ears or very few. No mickey ears means it's empty.
I use that to collect my credits each day, and, of course, to move around on a quest. Saves time and is less aggravating.
I hope it helps, and thanks to whomever posted it originally!
