It's too soon since he last slept for him to go to sleep again, naturally, unless he decides to cast another ritual for it. Which he doesn't. He is Mentally Tired of ritual casting, even though energetically, he still has plenty in his reserves.
He could go exploring, but it's about to be nighttime, and he doesn't know how safe it is to be wandering around at night. He is an experienced practitioner of the Way of Tranquility, but like, he doesn't want to get into a fight or get stolen from. So he'd rather not. He also thinks about poking and prodding things in the hotel room, but he fears that it will be like the windows earlier, where it does something he really doesn't want it doing, or like the shower, where it's deeply unnerving or disturbing or upsetting.
He will decide to follow the Way of Tranquility, which entails continuing to lay in bed doing nothing.
After thirty minutes of this, he realizes that if he sleeps according to his bodily urges, then he'll only end up sleeping several hours later, at which point going to sleep would mean he misses the noon meeting time. So, he ought to go to sleep now, such that he can guarantee that it will be before noon when he wakes up. Sigh.
It's very awkward casting sleep effects on one's self, but it's something he's very practiced in. He casts Rest and Repose very begrudgingly and very efficiently, and falls asleep.
