Reads like you had a great time.

Ive been lucky enough to have ridden the Katy once one way with a train ride at the end, and four times both ways from the very beginning to the the very end and beyond.
I just find it relaxing to ride without traffic and in(mostly)solitude, though I was run into by a teenager in a group who was looking at his phone once.

Every time I have ridden it I try to stay at different places. It makes the experience a little different each time. Of course you start to get preferred places to stay.
And even though I cook my own food, I try to eat at the various restaurants. Some are good, some not so much.
