C.P.
I say no. He came for the birthday party. She has school the next day. She doesn't want to spend the night. So see if he can come early to spend time with her before the party (maybe take her to breakfast on Sunday so you can get her party ready without her underfoot?). And he could take her for the late afternoon/early evening after the party too. But she needs to be home by 7:30 so she can shower and get to bed, IMHO.
