In the past 5 years, there has been no progress in low light photography.
You still need a DSLR camera for good low light shots.
The newer small cameras will let you select higher ISO settings,
any setting above ISO 400 will have excessive noise in the picture.
The Disneyland Main Street Parade (at night) is well lit and your present camera will do as well as any of the newer cameras.
A few tips:
If your camera has a viewfinder, use it instead of the LCD to frame your shots.
You can hold a camera steadier when it is pressed against your head than holding it at arms length.
Lean against a post, wall, doorway, etc.
For shots of LA at night, you will need a tripod to support the camera because your camera will have to select a slow shutter speed.
Some people carry a bean-bag and use it for a tripod.
You just need a place to set the bean-bag.
