Okay, thanks to everyones advice, I think I'll place them all in the same park, as it is, the park I have in mind is way big enough to handle this. However, it would be completable with-in 2-3 hours in the same park, unless I make the puzzles a little harder. Which I really don't want to do. I would also like to give a big "THANK YOU!" to everyone for their help. Thanks again,
