RootsTech has announced the addition of two hotels after the first two, the Salt Lake Plaza and the Radisson, both sold out. These two are adjacent to the conference center. I don’t know if you can still reserve at non-conference rates. They may be entirely sold out.
The two added hotels are the Little America Hotel and the Crystal Inn Hotel & Suites. I’ve not stayed in either one, so I can’t say much. Well, that’s not entirely true. I stayed in the Little America once back in the ‘70s. Yup. It’s that old. But it has been regularly remodeled. The best thing about it is that it is located near a Trax light rail station that is inside the free-fare zone. It’s a quick ride from the Little America to the doorstep of the convention center.
While the Crystal Inn is also within the free fare zone, there is no convenient bus route. Google recommends walking about three blocks (0.4 miles) to the Trax station (next to the Little America) and riding from there. The hotel does state that they have a free shuttle which runs downtown. I imagine RootsTech Organizers will make certain that the shuttle runs to and from the convention center.
