My gliders are napping throughout the whole night too (on and off). They get up and eat, then go back to pouch, then up and eat, maybe play a bit, seem to be curious about any activity if I'm in the room if they're up and not eating. Then go back to sleep, also chill in other hangout spots on and off as well.
They can get active when out of cage, curiosity mostly.
Maybe the difference in your glider may be that at first she had a lot to inspect, and now that she is familiar she is chill'n a little more.
What to watch for is changes in eating, poo & pee, drinking extremely large amounts of water &/or drinking water overly frequent. Look for brightness in eyes and over-all perky look, including ears. If all seems normal, than she's just settling in.
