We stayed at the Hilton Garden Inn last weekend for my son's wedding in Sioux Falls. I had made my original reservation back in April and then later added an additonal night and found the front desk and phone staff very helpful with both. Check-in and out was easy and our room and all the public areas were clean and very well maintained. Also, their wedding reception was held at the hotel and the food was delightful, service staff were great too!
Great experience overall!
