Whenever we have guests with us who either haven't been or haven't been in a long time, I like to sit back and let them drive the visit. Too much of me saying "You've got to see this" or "We've got to get to the other end before this show starts" can really turn the newbies off. It's kind of like sitting in a movie theater and telling everyone when the best parts are about to happen. I say that if they want to see a particular show or attraction, I can get them there pretty quickly. Otherwise, my suggestion is, let them know what is there so they can pick out what they want to see, and then get them to those places before the end of the day. It's kind of fun to see SDC through the eyes of a new person; in fact, it paints the place in all new colors for the veteran.
Also, remember the suggestion from SDC itself - go clockwise! Once inside go to the left first, down the big hill.
