as mpenza pointed out, it really does depend on the lighting of the room / area. ordinarily, jacking up the iso is an option (iirc the 5500 can only go up as far as ISO400). but you might still require mighty steady hands, pictures might turn out yellowish and grainy, and you must have cooperative subjects. also note the effective range of the built-in flash, it tends to be around 3m-4m only.
