Advice for families!

Stay as close to the Park as you can - it's good to be able to come out for a break without losing too much of the day. For most folks the three Disney owned hotels are expensive (about 3 times the cost of off-site hotels and motels) and simply not worth all that money. The off-site hotels on Harbor Blvd from the Howard Johnson's to the Candy Cane Inn are what most folks call walking distance.

Get your park tickets in advance - most hotels sell them at reception and this will save you a lot of queueing time before you get inside the park.  The best deal on multi-day ParkHoppers is buying them in advance before you arrive, Disneyland.com sells them and there are no additional fees if you opt for the Print at Home option (e-ticket).  You take the printed bar code directly to the entrance turnstiles for entry to the parks.

If you have a child/ren under about 5 - TAKE A STROLLER/BUGGY. Small children just can't last the pace and the amount of walking involved. Disneyland rent strollers by the day ($10) from a desk at the right hand side of the main entrance. They're good because they are large and sturdy even for older kids, easy to push, and in the unlikely event of a problem you just return it to the desk and get another one. They also have large storage baskets underneath the seat which are very useful. But if you bring your own, or buy one when you arrive in Anaheim, you can save money and also have the use of the stroller going to and from the parks, and for the rest of your trip.

Try to get into the park as early in the day as you can. Get to the "must see" rides and do them first before the lines get too long.

You are on Vacation, so do not rush things, taking a break in the middle of the day is a good plan for most folks.  Disneyland is at its busiest at this time, and going back to your hotel and grabbbing a bite to eat, taking a nap, or enjoying the pool is a nice change from the crowds.  Take your time, and enjoy your trip.  It is NOT a race.
