Just used Kids Exercise to run a 12 year old twin girls Birthday Party at Chowder Bay. There were 25 , 12 year old girls who were thoroughly engaged and entertained for a complete hour with many old fashioned sport activities. Tug of War - a huge success. Sack Race - hilarious!! Sandy and Fee were perfect and spot on with the girls. Would highly recommend Kids Exercise - outdoors, sport and friends - a winning combination. Kids Exercise were very professional in all my communications - great customer service!!
