What kind of hides do you have? Logs, coconut shells, boxes, etc? Most BPs don't like log hides, I know mine won't lay in them even if they're the only thing offered to him. They prefer hides that they can just barely fit into, or that they can easily touch all sides. It lets them know they're the only thing that could possibly be in there and helps them de-stress.
Activity at night isn't necessarily a bad thing. They're nocturnal creatures so if they show their face it should be at night. Quetzal's usually very active for an hour or two between 11pm and 5am, so that sounds about right to me :3 Active when you first get them is also a sign that they're just taking a little to adjust... they want to see what's in their new home so that they know the best places to hide and where to get warm.
It might take her a little to completely calm down after coming home. It'll take a bit before you see her true behavior, just let her chill and she'll eventually settle into her normal routine so you can see her real personality. I know a lot of people on here have a hands-off policy with their snakes until they get two good feedings in, which gives the snakes at least 2-3 weeks to settle before they start poking at them.
