Large rounded bags like the Plaza will tend to slouch a little at the bottom. I usually start out with the bag lying down, stuffed. I pat it into the shape I want it to be. After about 6 hours lying down, I stand the bag up overnight. In the morning I'll remove the towels and run them through the dryer. Then I'll restuff the bag and lay it down for a few hours, then stand it up for a while, then lay it down on the other side...just keep changing the position while it dries. When it's mostly dry I will remove the towels and let it finish drying.
