As a (former) professional mover, I have to say,....
Ha! ha! ha!...
No, really,.. moving sucks, and the best advice I can give is; don't try to unpack all in one day. Go one box at a time, and when you can't find that thing, don't panic,
it will be in the next box. Just go slow and enjoy the process.
I hope all goes well, darned shame I can't be there. Really mean that, I'm good at packing and organizing stuff.
(Other peoples stuff, that is...)
