It really depends on what you like. I'm not a sudden-drop kind of girl so I wouldn't go on Splash Mountain. I'm a big fan of Big Thunder Mountain and Space Mountain, and both rides can have long wait times. I wouldn't recommend any of the attractions that have continuous rides like Peter Pan unless you have a young child with their heart set on a certain ride. These rides typically have lines that move continuously as well. Except for the Haunted Mansion, the sun in that queue line can be brutal. Ideally, I'd use FASTPASS on Big Thunder Mountain, Seven Dwarfs Mine Train, and Haunted Mansion and wait in line for Jungle Cruise, Space Mountain, and Buzz Lightyear. If you don't care too much about the shows, parades, or fireworks, then you can get some short wait times for some of the most popular attractions.
