Chin playtime?

Hey! I was wondering how much time a chinchilla should have out of their cage? I only have one chinchilla (around 1 and a half y/o) and she gets around 5 hours of supervised playtime daily (8pm to 1 am). I normally chill and do work such for the first 2.5 hrs, then play with her individually for the remaining time. She never seems to get tired, though, so I was wondering if I should lengthen her playtime?

also, random question, what do you guys do in terms of your own housing? My college...
