Mercer/Grove City KOA is excellent. There are so many amenities. The swimming pool was awesome. All areas clean and well maintained. Our stay was great!

Nice stay, not many activities for kids and unable to use the pool due to rain. Overall a nice experience.

Had a wonderful time! Cabin was much larger than expected, staff was friendly and helpful, and everything was very clean! Great breakfast on Sunday also! Wished we could've stayed longer.

It was our first time staying at a Kamping Kabin - it was GREAT !! The Kabin was clean, spacious, had a TV with Cable and a stand fan that kept us cool at night. The campground itself was well maintained and 5 minutes to the Outlet Mall. My only worry now is KOA Mercer has set the bar so high that if we stay at Kamping Kabins in other KOAs we might be disappointed. WE WILL MOST DEFINITELY BE BACK!

We thoroughly enjoyed our visit! Mercer KOA had everything we were looking for in a family vacation! We will definitely be coming back! We have already recommended this place to many of our friends.

We was very pleased with our stay at KOA of Mercer. We have been to several KOA campgrounds and the cabins we stayed in was not near as clean as yours. Everything was Fantastic and would refer you to others to stay with KOA Mercer. Thanks Barb Garcia
