I also wondered how to bring my luggage. We would have sleds, so it didn't need to come in a backpack. Maybe a duffel bag? These give easier access to the luggage. I decided to go for it, even though mine has nothing to make carrying it easy.
When I walked to work in the morning, luggage and all (I would leave for the airport after work) I chose to carry the bag on my head. It seemed the easiest option! And it attracted attention. Soon a car stopped and offered me a lift. So nice!
When I left for the bus station this did not happen, but once there, I recognised an MSc student I had once taught. He helped me with the bulky thing, and even helped me carry it to the ticket machine at the railway station! What a nice man. He even confessed he had walked into the wrong room that day I taught him; he was a marine biologist, specialising in jellyfish... nothing I have much to add to.
Made it to the station!
My rather heavy luggage
Getting to my hotel at the airport was a bit of a nightmare; it was undergoing maintenance or something, and many passages were blocked. I had no pound on me for a trolley. I had misinterpreted my notes and ended up at the wrong terminal. But I got there! And after a short night I was ready to check in. It will be nice when after eating all the food that bag will be lighter on the way back!
Anyway; some of the worst was over (travelling back will be a chore too) and soon the fun could begin!
