Sounds like fun. A pool table could make an interesting competitive game location.
As to the bowling, I think it work best if the "alley" was elevated with the balls sticking up through a hole in the alley.
I've often thought that corn hole, "bean bag toss" could make a fun competitive game for teams of girls to play. Instead of a hold for the bags to fall through to score points, balls stuck up through a smaller hole would be a much more interesting target.
