Based upon last year, these shuttles will be full and there is no doubt many use them. Which is one of the reasons MFF brought them back. But they don’t cover all the hotels in the area sadly.
All you need to do is find the convention center 5555 River Rd in Rosemont and search for nearly hotels. Now you see the issue, Uber, Lyft and taxis get a lot of rides during the convention. It’s not that there is a long wait. I think the longest we waited last year was about 15 minutes. But more often you will get a message they have to drop their current passenger off 1st. The ride is generally for me under $8.
But the shuttles don’t stop everywhere. Already I am seeing complaints that even if their hotel is on the route the bus doesn’t stop there.
All I can say is the local bus PACE charges $2 per ride and the one that goes up River Rd, runs about every 30 minutes.
You might think I added the last one as a joke. Yes fursuiters have taken that bus, There is a stop outside the convention center
