Gail, check out the Clarion St. Charles. We stayed there a couple of weeks ago for a football game. The rooms are not large, but nice. The beds were fantastic. I'll stay there again just because of the beds.
We paid less than $90 for a night, that included taxes, parking and all the other charges they could come up with.
I would guess it is a 5 minute taxi ride to the pier. I don't think they offer a shuttle, but you should ask just in case.
