Sure
Go to the store if you are looking for a quick answer/fix and they will try to help you. Otherwise call for an appointment.
Only way to find out the answer to that one is to call the Apple Store, get a genius on the phone, and see what's where they're at with appointments. My guess is maybe, possibly, though it's unlikely. I've probably made three or four appointments there over the past five years and pretty sure all of them ended up being 2 or 3 days out.
