Upset with Hotels.com

It was a shock to check in. I’m struggling to walk and have to use a cane. I had to walk up a flight of stairs to the registration desk to find out my room was another room upstairs. They were saw how I was struggling walking and offered to trade my room for a room that was on the main floor. Sam also helped bring in our luggage and offered to help me up the stairs. The room was advertised ( by Hotels.com) as having spas, massage and soaking rooms; which is why I made the reservation. The description did not say I would have to navigate 2 flights of stairs to use them. I left a message for an ADA room. Management said they sent a message to but I didn’t receive it. It wouldn’t have mattered because the reservation was non refundable. Breakfast was included in the price of the room. Breakfast was short on selection, delicious but was not great if trying to watch your weight. I’m thankful for the people that worked there for trying to make me comfortable. Im extremely upset with Hotels.com for not stating on the main page that there are stairs everywhere in the description. Nor did they make any effort to show the stairs in the photos; they were shortened to edit out. I wish I would have taken pictures that reflected the true conditions.

The property was convenient to the river for tubing, hot springs, and food options. Parking was close and free. The hotel was very quaint and quiet, and we appreciated the gift of a discount for tubing, the free use of hot springs rooms onsite, and the tasty breakfast that was included. There was even a room upstairs with jigsaw puzzles. :)

This is an old beat up hotel past its time. I'm sure in the early 1900's it was great. Old and tired.

Hot room

The portable air conditioner never cooled off the room. It was rough sleeping conditions. Other than that, the room was impeccable and service great.

Historical building with upgraded rooms. Clean and comfortable. There was a portable AC in room. Mineral pools are private and clean usage on first come first serve. No extra charge. Robes and towels provided. There is a restaurant but prices seam a little high. Live music on Thursday nights. Main Street close by. Public hot spring close by also. Front desk host was very friendly and informative.

Overall it was nice, but they do some really odd things badly. The bed was not comfortable and seemed smaller than a queen. The shower curtain rod is cheap and fell down 4 time (spring not bolted down) no vent fan for bathroom but there is a heater? The door to our room was kinda hard to lock or unlock. The free breakfast was disappointing small and not all of it made there. Staff was very polite and friendly. Neat old building with some great seating areas. Overall I was disappointed I thought they could have done better

We stayed for one night on our way back from Rushmore on a road trip. Our plan was to stay next to the hot pools in Lava Hot Springs since we got online tickets to use that facility. The Riverside Inn is a historic property conveniently located with a friendly staff. It wears its age well but it is part of the experience. It doesn’t have elevator or luggage cart however the staff offered help with our bags which was very nice. Dave went above and beyond to make us feel welcomed in the property. We tried their Portneuf Grille&Lounge and were amazed with the espresso drink prepared by Will. The breakfast was cooked to order and delicious, thanks to Colter and Alexa for making it so enjoyable. Overall we had a great time at the Riverside Inn.
