Reading your question I can be a little help. Not sure what activities they have available this time of year. I doubt you would be swimming. They do have playground, putt putt and you can rent peddle cars. When we were there is was fall and they did bring out the characters on the weekend and they had the train ride. During the week not much going on.
Overall the campgroup is nice but some of the sites are a ways away from the bathhouse. This would include walking up a hill to the bathhouse. I forget the site number we were on but we were close to the main house.
We didn't find much to do in the area so be prepared to hang out at the campground.
Sorry could not be much more help.
