We are currently staying at a new Columbia Sun RV Resort in Kennewick, Washington.
It is a beautiful resort with 145 sites covering 25 acres, 87 of which are pull-thrus. Most of the sites are over 70′ long with several over 100′. There is lots of grass and first class amenities, including private showers and bathrooms at both ends of the park and each having laundry facilities and one a game room and the other an exercise room with first class equipment. Also, there is a 3000 sq. ft. event center with multi-media facilities and a warming kitchen. The WiFi is awesome with 100mbs down at the server.
Would highly recommend this park to anyone passing through the area.
