We will be in Vegas for 6 nights in December. I've already booked a compact ... we normally go with National, but are holding three reservations using existing discount contract IDs and coupons:
National $216
Alamo $199
Budget $181
Both Alamo and National are owned by Enterprise and, basically, operate as one company. I will continue to periodically check the rates, as I normally can get a one-week compact for that same week each year at about $150.
Compare that to my upcoming 1 week rental in Orlando at $88 !!!
And, yes, you need to take the shuttle to the car rental facility off-site as mentioned above.
A different market and we will be there the week of the National Rodeo Finals.
