Does the Golden Spike have a free breakfast? The HI Express does. With a family of five, this is always important to me.
Just a FYI, you only need to post in one forum. I think everyone on here just checks the South Dakota forum and when they do so, all other forums are visible.
We stayed at the HI--nice people working there, clean rooms, adequate breakfast, evening happy hour type thing with free beer, wine and soft drinks, which was a nice touch. The guest coin laundry came in very handy for us as the nights we stayed there were mid-way through a two week road trip. Short walk into town for shops and restaurants; conveniently located for the grocery store. I would stay there again.
No experience with the Best Western.
I have no direct experience at either one. BW and HIE are rated #1 and #2 respectively on this site for hotels in Hill City. To me, it would be a toss up. I'd probably go with the more budget friendly of the 2. Both seem to offer similar amenities.
The Golden Spike offers a breakfast. The rooms are basic but clean. They are pet friendly and offer a nice pet walk area.
