Honeyduke’s.
I have a sweet tooth, what do you want?
I might spend my time at the Yule Ball. It would be lovely to see everyone dressed up and looking fine. Except poor Ron in his ‘dress robes’
Well…
Super obvious!
The Room of Requirement.
It’s whatever I require!
Might as well be a god damned magical holodeck!
Alternately, I kind of like their Tardis-like tents, one might be useful for a week at Burning Man.
Thinking more about it… wow harry Potter didn’t really have many appealing specific locations. The mythos as a whole was appealing, but not on a small scale.
So your magic is able to transport me anywhere at all, without fail, and then get me back a half-hour later?
Ok, take me to Gringotts Wizarding Bank, Vault 713.
That should take care of my money problems for the rest of my infinite life (if I can figure the elixir out).
And yeah, like they will even suspect a muggle of being able to get close…
I think I’ll be on the Hogwarts Express, enjoying some cauldron cakes, pumpkin juice, and chocolate frogs.
