When planning a visit to the Disneyland resort, it is a good idea to check the Disneyland and California Adventure park calendar. This way you’ll be able to see which rides will be closed for refurbishment. Park operating hours and any special events that may be planned for the days that you plan to be in the Parks. If you are able to be flexible with your vacation days, you will be able to minimize the possibility of disappointments from having your favorite rides closed during your visit.
You can also check to see if there are any special events planned around the time of your visit, that may increase the Parks attendance for those days. As I have said before the best time to visit Disneyland is when most people are busy with work, school, and other things. This leaves the park yours alone (almost), to enjoy in any way you feel best. Shorter lines, quiet resturants, and shops and stores easy to move around in.
