Beautiful resort with large grass area between sites; plenty of activities for children; close to shopping and museums; on site fuel station. NEGATIVE: Cable was not working at our site; we reported; waited almost two days for correction; staff didn't seem to care about the inconvenience.

The staff was super nice and helpful.The entire facility was exceptional. Everything was well maintained and clean.

While it was cold and windy, we found the park to be very nice. The people that worked there were very helpful and very cordial. Located close to the Isle of Capri casino was also very convenient. We were only passing through and stayed overnite. We had a pull-thru with full hookup, site was good and all of the utilities were located for easy hook-up and unhooking.

The campground was awesome. Very clean and friendly. The only reason we did not rate it 5 stars is the distance you have to walk to get to a shower. Had Sr Citizens with us and unlike every other KOA that we stayed at, this one's shower was a long walk that at night was not lighted at all????

Arrived in rain. We were surprised and disappointed, with a park this large, there was no escort to our site. After a maze of turns, we found our site...with a huge, heavy picnic table sitting in the middle of the drive. We had to drag a 200 lb table out of our way in pouring rain!!!! All of the sites around us had tables in their drives. Someone's a real jerk!

Misleading in description for casino and water park . You can't really walk to either. No heat or air in restrooms/showers. I needed heat for this trip. Seemed more focused on convenience store/ gas station than K0A campground .

Always a nice place to stay and visit. Staff was very friendly and helpful in checking in and also buying some food items at the store.

Having a store and gas station right on the grounds was great. Beautiful facility, friendly staff who made us feel welcome and clean facilities. Should mention the easy access to major roads.

Large, spacious and new. No signage giving directions to campground. Most sewer sites at road rather than at mid-site so bring hose extensions. Wi-Fi was erratic to non-existent. Laundry was dirty and buggy and dryer lint screens were full.

Everything was awesome. The people who took care of my transactions were great. This is a great place!

It was wonderful. We have been before and we will retune again. It is clean and quite. We will be back because both of our boys are attending UNI. Better then a hotel in my opinion. Thank you

nice location but the showers were too hot and the area around the fire pits was very unlevel, hard to sit around.

Everything was great!

The only reason I didn't give 5 stars is because the wifi did not work really great.

Traveling back to Mn after wintering in Biloxi Ms. Friends told us about new KOA, perfect loaction for final stop b/4 home. We were so very impressed / great staff, great facility, never seen a KOA that offered so much, plus a gas/diesel station! We will be back!!!

fine campground. early season visit and they were ready to be top notch.
Apr 27, 2015
This is our favorite KOA, we recommended to friends in Biloxi, MS and they stayed on the way back to Minnesota and loved it!! Great group of people working at this park!
Apr 21, 2015
First off, the KOA was beautiful, my wife and I enjoyed our stay. Our only problem was when we made our reservation they didn't tell us that the showers weren't available. They did offer a cabin to shower in but it didn't have hot water. I hope the park works out these d4tails.

Great Facility and the staff was awesome.. Very nice campground.. We will be back!!
Apr 09, 2015

Our last night on the road this winter was great. This KOA staff went out of their way to make our stay great.

This is the best campground ever. We were there in the winter and I can't wait to go in the warmer weather. The camping cabins are so cute and they are situated around the lake/pond. The small beach area is great also.
Mar 26, 2015
Wonderful to have a campground for a one night stay when traveling through-and open all year! Great! We will definitely stop again, nice level spots and full service campground.
Mar 24, 2015

Nov 16, 2014
a beautiful park rather unique
Nov 15, 2014
Excellent facilities would be wonderful in summer Unfortunately the bathrooms with showers were closed while we were there. I think that the website should indicate that all facilities are not available in winter months. Staff was friendly and extremely helpful
Nov 12, 2014
Clean and very close to many shops, restaurants, a small lake, a casino and a water park. We will return in the summer!
