My son (16) and cousin (12) want to tackle all four parks in one day. Just Visiting all four is too easy and riding every ride in all four parks would be impossible. My son thinks my suggestion of hitting all four parks with the requirement of riding one ride in each "land" is too easy. They have their day picked - May 30. EMH morning at DHS. No Late EMH. Hopefully MK will be open until midnight. Anybody have any suggestions or feedback on a reasonably tough challenge.
