Thanks for the advice guys. I wanted to go the Airbnb route to save money. I was just afraid to commit to it without some reassurance.
We had a group of gals from United who did the Airbnb thing; they had a house over Tamarac (about 20 min from Sheffield), and it worked out well for them. They split the house rental four ways, so it DEFINITELY made the most financial sense for them.
I stayed in the Sheffield housing. It didn't occur to me to do Airbnb; I'm familiar with it, but I've never used it. I had a single room to myself on the other side of the house. I had my own stove, sink, etc; it was like a mini studio, and I liked it. I had a nice desk and chair in which to study. Everyone here kept to themselves pretty much. At times, a couple of my housemates would study at the dining room table, but they were quiet when they did. BTW, there are rules about being quiet in the Sheffield housing, so as to promote a good environment for studying and learning.
Either do Airbnb, or the Sheffield housing is an option too. Either one will be WAY cheaper than staying at a hotel! A couple of my classmates did that, but their companies were paying for it. I ran the numbers on that, and I decided against that right away.
Oh, and one other thing: please study ALL of Sheffield's ADX study materials BEFORE you come! Even if you have to take a later class to do that, do it. You want to be in position to either take the ADX before you arrive, or take it immediately after you get here. I studied all the materials, and I took the ADX the Sunday before week 3. Getting the ADX done quickly DEFINITELY made my life easier! Some of my classmates failed the ADX, so took it again in week 4 and 5; many of them washed out of the class-so close, yet so far...
With that, I wish you good luck at Sheffield. I have to get to sleep, because I have my practical tomorrow...
