So I have never been a camper at windells. But I live pretty close and I am always attending there open skate sessions on Saturdays.
1. Most likely there will be a mix of campers from male to females staying with you. They seam to have a variety of campers.
2nd When I attend there open skate sessions it is defiantly so much fun. There indoor skate park is awesome. The trampolines are really fun too. I wish they had a little more area for the trampolines considering there are only 2 tramps and 1 foam pit. Which you have to share with the incoming bikers/skateboarders. The outdoors skate park is also alot of fun as well as the dry slope until you fall on it. One good dry slope burn and you will be done for the day. There are also dirt trails and jumps for bikers.
With the awesome parks and recreation you will most likely have an amazing time if you do attend. Also being able to meet new people and go ride at Mt. Hood. Windells also has sponsors who attend the camp during that session. Doing games and giving out prizes to the campers.
If I had the money laying around to go. I would not hesitate at all.
