I used the Independent Tourist for a self-guided tour of Katy Trail which included the shuttle from end-to-end and daily luggage shuttles. See:

I was very pleased with the Shuttles and the accommodations. A couple of the B and B’s were outstanding and one was disappointing and I know that they followed up with what we said we weren’t too happy with. This was a couple of years ago and I thought that if I did it again I might contract just with the shuttle provider (whose name I no longer have) and reserve my own bookings to see how that compared. This was my first experience with a self-guided tour and there isn’t much to it when you start at one end and finish at the other end. But I was very satisfied with the overall experience and had plenty of time to check things out along the way. I enjoyed the dining and the wine tasting that the Katy Trail had to offer.
