Downtown Disney district sits in between Disneyland, California Adventure and Disneyland hotel. The area is full of entertainment venues and restaurants.
The best things are free at Downtown Disney: You can stroll around, enjoy the scenery or listen to street performers. At around 9:30 PM you can catch the great fireworks display right from the district. The fireworks are launched above the sleeping beauty castle, but very prominent from several locations in the district.
If you feel like a big spender, you can indulge yourself with fine dining and happening shows.
