When we were first there I had it all planned but by about the third day we kind of took it as it came. Before we went I spent aged looking at tour plans.
I think being there for three weeks gave us a little more time rather than rushing around. Somedays we just went late to the parks and enjoyed the rides in the evening. Other days we would aim to go early then have an easy afternoon. If the rides were busy we just came back later or try again another day.
I must admut I do tend to route march everywhere which drives my DH mad, but I've always done that. My DH is so laid back he is usually horizontal.
