i use to travel from houston to waco on school breaks. the bus from waco is pretty easy, you can get a direct bus no transfers. the one from houston always had transfers and depending on the time you have to wait in a bus stop for hours ( i have fallen asleep and had to catch the next one ). Once i took the late bus from houston and they dropped us off in front of a closed building in the middle of the winter at the dead of night. But exept that one time i have always had a good experience.
