Here's Robert's, Shoo's & my WoW characters "resting" in the Inn in the undead Undercity Inn. Nice beds, huh?
If you park your avatar in one of the main cities or in an Inn, you earn a bonus for your experience. The experience bar will be blue when you're earning double experience. It's purple for regular. I play almost solely in the blue. I will change over to a different character if I catch up to the purple.
