I go into the parks alone because my wife likes to relax and doesn't always want to go on rides. We meet up later. I have no problem doing this AND...without others slowing me down...I accomplish alot.
I even like sitting on a bench and looking out over the parks. It's a thrill just being there...
I love going with my family but I would love to go one time by myself. I am a detail person and get a kick out of the many layers of detail that each park and resort has. But it is tough to get my four year old and my six year old to remain patient while I stare at every nook and cranny.
