Disneyland can be very crowded if you're planning to visit on weekends or holidays. Which in turn makes the waiting time so much longer. Be sure not to miss the fireworks at night because it's really magical! If you can, stay one night at Disneyland's hotel to also enjoy the view of the fireworks! But please be sure to enquire the hotel staff for the view. There's also many shops inside selling many souvenirs which is what I like the most about! However, you can't bring certain things inside such as beer etc etc. (They will check your bag before you can make your entrance, which is a bit troublesome.) But there's a locker service just beside it just for a small fee! It's easily accessible.
