Worst possibility first:

Check your antifreeze level and check it for oil while your there.

You could have a cracked head gasket and be sucking in coolant.
Pull each sparkplug and see what it looks like. If all are slightly
sooty and one is squeeky clean, that's the cyl that is sucking antifreeze.

You don't say how old it is, new exhaust systems will smell funky
till the machining oil burns off and the metal carbons up.

A failing catalytic converter usually smells like rotten eggs

Good idea, it doesn't have any classic signs; very little smoke at start
up, none visible while running, no odd temp changes or overheating
spikes. I'm definitely keeping an eye on the coolant and oil though.
Last I checked the oil and coolant was clean, and the plugs looked fine.

I've smelled this on a lot of jeeps (but not all of them) it's
definitely more of the sulfur rotten eggs thing... But it's more like
the exhaust just has MORE too it, amplified if that makes sense.

A CNN article yesterday said many hotels have bedbugs, and that a 'sickly
sweet' smell will be present in the room.
Check your seats!!!!
