Sounds pretty normal to me :) "Play time" is their play time whether its in the cage or in the bathroom. It's their most active time and time to explore. They don't usually want to cuddle or be held when their awake in cage or out of cage.
While she is probably having a blast exploring, you probably aren't lol bring a book or laptop in the bathroom with you so you have something to do also. Sometimes occupying yourself rather than trying to interact with them will make them more curious about you and what your doing. Making the critter come to you to check you out more, which is what you want them to do ( come to you on their own ) she still probably won't want petted or held so just let her be on you without reaching for her immediately or just offer her a treat when she is on you.
Mine pretty much stay on me even in the bathroom, they play with my hoody strings, groom my hair n eyelashes jump from one hand to other... I also bring a couple of their fav toys in the bathroom with us and snacks n my camera lol.
Sleep...my female wakes up fairly early anywhere from 7:30-9 pm, my male doesn't get up until 9:30-10pm which is probably more normal. Even though Leela does her best to wake him up ( usually by relentlessly jumping on him and the pouch )
Both are usually back in the pouch by 6-7am with an occasional nap in between. Usually if I can't sleep n think well I'm up I'l go play with the cridders at 2am then their nappin or grooming in the pouch so I go back to bed lol
