TZoom;
As a Salt Lake Bus Operator for UTA(Utah Transit Authority)or as Wes call us,(Unknown Time of Arrival) our last Weekday bus leaves the Intermodal Hub at 10:45P,arrives at SLC Airport at 11:05P. However this time may change come April 4.
The Hub is not the best neighborhood late at nite, but as mentioned, cabbies usually hang out in front all nite. A trip to Airport will run about $25. As you know, if you spend the nite at a Large Downtown Hotel, they'll pick you up at Hub, deliver you to your Hotel, then take you to airport or wherever the next morning.
Enterprise has a rental desk at Best Western Downtown SLC. 122W S. Temple 801-539-7752.
Just do like Dan Warner, don't tell them your taking the car to the salt, but that your going to visit your sister in Ogden! LOL
Good Luck, hope to cya on the salt!
