Just to name a few (all were bike friendly), we used the:
Peabody
Memphis, TN (e/r to Sturgis 69th)
Hampton Inn
Deadwood, SD (12-miles from Sturgis), 5-nights
Cody Inn
Cody, WY (2-days, base for running Beartooth, Yellowstone and Grd. Tetons)
Mirage
Las Vegas, NV (gambling, rest & relaxation, 3-nights)
Various Best-Westerns, Embassy Suites and Hampton Inns in between.
Deadwood-Hampton was pricey (as can be expected at Rally-time) but a good location and good center of the Black Hills if you want to be out and away from the mainstream of the City of Sturgis or the larger camps, i.e. B-Chip. Its all about what you want isn't it. Sturgis was a stop-over for us and part of a 26-day, 3700 mile "big circle" tour that all began from and ended in Houston.
