Being a Disney fan I could not pass up visiting the park at least one day while visiting the LA area. Since we were only here one day we decided not to upgrade to the one-day park hopper, although in the end we probably should have. If you just go to Disneyland for one day with someone in a wheelchair it can get boring because you easily get on every ride you want and have you list done by noon. The only ride that we waited forever was Pirates of the Caribbean, which recently reopened with Jack Sparrow animatronics. That wheelchair line took us almost two hours, but it was worth it and I have no problem waiting the same amount of time every one in the regular line was waiting.
The first thing we did at the park was head to the VMK booth in Tomorrowland to turn in some quests I printed off at home and found the answers to online and do the ones that are handed out in the park, which I also had brought the answers from online with for. By doing any quest you get a glow-in-the-dark wristband and depending on the quest you get different cards that have codes that can be redeemed online for virtual items in
www.vmk.com For each quest the prizes are awarded to every one in your party, as long as you have their park tickets with you, so do not worry about filling out five of the same pamphlet for you party unless the kids each want to have their own then definitely let each have their own fun finding the answers.
For most visitors one day in Disneyland is enough, especially if you stay from 8am to 11pm like we did. It really depends on the age group you go with. Some young kids can enjoy going on all the rides in Fantasyland over and over, but parents may get tired of that and sometimes the lines can be really long. Older kids may get bored if they are only into the thrill rides. If you park hop and are visiting during peak times than several days in Disneyland is necessary to do everything without becoming bored. Do not just ride the rides, but also enjoy the great parades, shows, and fireworks.
