I was told that the buses stop at the Longhorn Restaurant. You must purchase your tickets via the website and print the ticket out. You must have the printed ticket in order to board the bus. You must also have a picture I.D.
A bus going north stops at the Longhorn about 2:50 p.m.
Buses going south stop at 1:00 am and 1:55 pm. That is all the information I could manage to extract from the human I talked to. Most of the time all you get is an automated message system.
The ticket is only good for the Date and time it is designated for.

GOOD LUCK. Its a little confusing.
