Ah, Carrie. How she has grown. First she was a babysitter. Then she was a preschool teacher. Now she is a camp counselor. The gameplay is the same as the other two. Drop the waiting kids to their seats, bring them the things they need, hang their finished project (in this case, tie-dyed shirts) to dry. The most complicated part of the game is trying to get everything done before the kids get angry.
I found this version to be more enjoyable than the preschool version. The things you were asked to deliver to the children made sense. You weren't asked to do things that they could do themselves. There are also some slight additions to the game. Some of the tables have two seats. Those tables require two people to be seated before they will start the project. If you don't have two children available, you can pull another counselor in to help the child. I didn't find it particularly necessary though. You know that those tables need two children so you just try to wait until you have two children. Otherwise, sit them at the one-person tables. Not a difficult task.
This series isn't my favorite time management game but this particular one isn't terrible. I wouldn't plan on wasting a lot of time on it though.
