Lucy, assuming you were asking about the sleeping accomodations, in general, you will only find ADA compliant facilities in the newer hotels (since ADA didn't go into effect until the 90's). Most of the B&B's are large, older homes in which it would be economically impossible to bring them up to compliance -- a wheelchair ramp to the front door is easy, but bathroom modifications are not. The Comfort Inns, the Holiday Inns, etc. are all compliant and have special ADA rooms with the roll-in showers. But they might have limited availability, so call way ahead of time.
If you were asking about restroom accomodations along the trail, in my recollection, most of the facilities seem to be ADA compliant. But that would be a good question for Dawn Frederickson at MO State Parks.
The trail itself is finely crushed limestone, so it can be slightly bumpy and dusty, but I have seen scores of wheelchairs on the trail, especially around Frontier Park in St. Charles.
