When I walked into the reception hall the evening of my check-in, I had to say "Hello, I have a reservation" to the lone receptionist who was standing there staring at me (no, he wasn't on the phone). His attitude seemed almost fearful and certainly unprepared. I struggled to hear him, he did not tell me my room number, and did not give any kind of explanation about the elevator. I have used secure elevators but if my mother had encountered that system she would have been stuck and then had to ask for instructions (embarrassing for some). Later the same front desk person again stared at me in an almost creepy way as I went to the pool. When I attempted to call room service later he answered, because the room service number wasn't working. Yikes. That call was followed up by a very aggressive server from room service, who rang the phone continuously until I picked up (I was on my mobile and figured it would go to mail. It didn't; instead she just hung up and redialed). The room itself was OK (boring decor but comfy bed), but I was almost glad my very tall husband had stayed home as two of us would have been very cramped indeed. In fact I had a king bed and river view, erroneously thinking that this room might be spacious. I was wrong (river view was not impressive and not worth the expense). Another tip regarding the rooms: bring slippers! The floor is tiled in the entryway through the bathroom and it is cold!! I called guest services late at night and again, the person who answered seemed to be sleeping. Overall, this experience put a slightly bad taste in my mouth. The hotel felt desolate, almost like a ghost town by 9 pm. I know that it's new and it takes time to work the kinks out, but I would have hoped that the biggest problems would have been with things like the television, not the hospitality of the staff. My advice to myself and you, reader, for the next stay in Sioux Falls? Stay at a different, reputable hotel, and save $50. Heck maybe we'll even get a complimentary breakfast or newspaper in the morning - things you don't get at the Hilton Garden Inn.
