My first bus traveling experience would be considered a breeze! I called in and they accept phone orders with a valid credit card, and I was quoted $90 for a round trip at a student rate from Las Vegas to San Ysidro since I was going to TJ for my brothers birthday! Upon picking up your ticket, its easy at the ticket booth and you wait 10 minutes until your departure to start boarding.
The downside is that the bus goes to the strip and boards additional passengers, so you have to be patient as suppose to going directly from Tufesa to your destination.
The one of the best perks are the Wi-Fi on the bus!
