Use a three wick plain candle. It works, trust me.
Also, I have a smores kit. I got it a couple of years ago for christmas - it is wonderful. Basiclaly it is one of those little burners you light and use in a buffet to keep a dish hot. you place that in a little container with a grate over it.
However, I know for a fact that three wick works, and flame me - but I have taken one to a hotel before. I am a smores junkie.
