1 day is definitely not enough to cover the whole disneyland...one must plan for 2 days and stay the night at the disney hotel..its very near to the park and you can take shuttle service...if even you are planning a day trip i would suggest you get a fast pass ticket so that you do not have to wait in the queue and you can cover more rides..coz with the normal ticket you have to wait atleast for 20 mins for 1 ride..... once you enter the park take the map handy else you wont be able to cover up all the rides and shows...start from the sleeping beauty casttle area that is very beautiful...and make sure you are at the main street at 12:45 and secure your spot beacuse at 1 pm the disney parade starts...loin show, mine ride are must dos...and click you pictures whith disney stars before 7 pm beacuse it closes at 7 and then again at 7:45 there is night parade which is wonderful and you cant miss..again you have to secure your spot bit early...and then at 9 pm amazing fire works at the sleeping beauty casttle.
