Turns out we had a guest on the bus with a ticket, but she was not 'in the computer' and they had to re-register her. The bus left more than 30 minutes late because the driver (Earl Denton) and the ticket office could not get their numbers to match. The round-trip fare is $5 all seems reasonable. Took the overnight Greatland Tours bus from SW Houston to Grand Casino Coushatta Saturday night of Mother's Day weekend.
