Are you asking for a hotel near the Hopkinton marathon start? If so, I don't think there are many hotels in the area close enough to get to the starting line without using a car. Instead, the vast majority of people stay in Boston and take the BAA provided shuttles to the start line: https://www.baa.org/races/boston-marathon/enter/transportation. That way, when you're done running, you don't have to worry about how you'll get back to your hotel all the way back at the start line.

The Korean toast food stand is not where all of the other food stands are. In fact, I missed it initially. It is to your direct left as soon as you enter the store. It's where they used to have the jewelry stand. That little connecting hall to the left of the entrance that connects you to the cash registers? Right there, at that first left corner. If you're at the bulk ordering stand, you've gone too far.
