Oh. Yikes. Dunno if I can find a dolly with such short notice.
You can actually rent stuff like dollies and hand trucks from U-Haul and probably similar places, so maybe give that a look?
Managed to get everything into two wheeled luggage bags and only two boxes, so don't need my usual dollie wheelie this year. If I wasn't coming down with a bug I'd contemplate bringing it anyway and rent it out hurhur XD
