Sarge:

As far as I know, the free trips, Las Vegas to Laughlin are a thing of the past.

We always rent a car when in Las Vegas, normally the first 15 - 18 days in
December. Laughlin is just under a one hour drive from Las Vegas.
Most of the casinos are connected by a walkway along the river bank behind
the casinos

The Gray Line Bus has a deals from $14 ... Included is:
#1 - Complimentary Las Vegas hotel pick-up and drop-off included
#2 - Depart from our tour center after check-in, located just minutes off the las vegas strip
#3 - Travel aboard our fleet of deluxe luxury motor coaches - all motorcoaches are equipped
with air-conditioning, restrooms, panoramic windows, & television monitors
#4 - Free Show Tickets with All Tours
#5 - $5.00 per person food credit voucher
