I took the family to see Disney on Ice a while ago. On such occasions, the primary thing is the family experience, so I do not haul my regular camera along with me. Instead I use a Powershot G16, which time and time again proves to be a very capable camera.
It shoots RAW and handles high ISO reasonably well and has support for full manual mode.
The rangefinder isn't worth mentioning though.. ..oh wait.. I just did, didn't I?
