Hold up -- are you thinking he'd arrange to visit Laszlo's again?

That seems like it should be possible, unless Alice doesn't want to let him visit 12GP. Sirius, what do you think?

The thing is I can't imagine he'll be able to persuade his keepers that he wants to spend every day of spring holidays in the company of the Laszlo's staff. It won't work, not as a method of bringing him for two weeks of lessons. It might be rather nice to have him for a visit, and he wouldn't need an excuse to bring you along.
