There would be room for improvement on many lines, particularly the Strip. Some lines need to keep shorter 40 foot buses on them so the Strip can be an all artic line. This would allow boarding and discharging on all three doors. There is talk of Las Vegas getting a monorail along the Strip, and if the plan becomes a reality, it would be a big help. Las Vegas is a great place to visit.
Hotels there are generally cheap, and of course Vegas has plenty to offer in vice-based enjoyment.
For the residents, the cost of living in Las Vegas is pretty low. CAT is an excellent bus-only transit system for the area. A visit is highly recommended.
