As Soon As You CanYou'll get the best rates on airfare and have the best chance to find that hotel room you really want if you reserve these as early as you can.
In the past few years, Disney has also introduced a mid-year ticket price increase, so buying tickets as early as possible could protect you against that.
One Month Before You LeaveYou can't do these earlier, but now is the time. Make reservations for sit-down dining at the Blue Bayou, Cafe Orleans Carthay Circle and Wine Country Trattoria. Now is also the time to reserve for a character meal inside or outside the park. One-Stop Disneyland Vacation Reservation Page has links and phone numbers to help you get this done quickly.
For flights to Orange County on Southwest Airlines, get your tickets within the next week to 10 days, before the fares start going up.
Two Weeks Before You LeaveSit down with your kids or companions to talk about what you want to do. Measure your child's height before you visit and check the Disneyland and California Adventure ride descriptions so you'll know which rides they can go on.
One Week Before You LeaveIf anyone in your group is prone to motion sickness, stock up on your favorite remedies.
Print your Ridemax itinerary if you're using it.
Print your eTickets if you bought them online, or be sure you know where your paper tickets are if you had them delivered. And if you're flying to Disneyland, put them in your carry-on, just in case your luggage decides to vacations somewhere else.
Print your hotel and flight reservation confirmations and pack them to take along. Print the directions to your hotel, too.
When You're Ready to Pack for DisneylandCheck the Forecast: Generalizations about California weather are often wrong. Take a minute to find out if the weatherman is predicting a heat wave in January or a deluge in July - and see what to pack in each season. Review the Disneyland tips for more ideas about what to bring (and what not to).
Drain the Rain: If you're traveling in winter when it might rain, umbrellas are hard to manage. Pack hats or raincoats with hoods instead.
Shun the sun: Bring waterproof sunscreen, hats with a cord (so they don't fly off on a ride) and sunglasses, especially in summer.
