Every gas cooker I've owned had spare jets to work off propane as well. Depends on the policy wording, most of them get twitchy about gas bottles inside.
I'm not sure what their reaction to making creme brulees might be.

One thing to remember about propane is that it's heavier than air, so will flow down and pool at the lowest point in an enclosed space - as marna says it's especially dangerous on boats where it's often used as cooking fuel and the bilge is a perfect place for it to gather undetected... until you strike a light. Good ventilation is essential - and maybe a gas detector too. At the very least, you should always turn off the gas tap on the cylinder when not actually in use.

You can at least smell leaking gas though
