Thanks for the suggestions so far. It's only a short trip (7 days) so I could survive without it if push came to shove. Ideally, I don't really want to buy a new stove to take the French 'push-fit' canisters, as that means I have to take an extra pot and it all adds up in space used. I'm only taking a day bag, but will consider it if all else fails.
Truth is, I just love my Jetboil. I see it as a 'water boiler' pure and simple - and it's fast! I can use it anywhere without looking like I'm 'setting up camp' - shopping precincts, bus stations, even handheld on a train! Perfect if you don't like paying tourist prices around Europe. But for Morocco, I thought it would be handy for the few times I'm on my own between towns and villages.
I've a feeling I'm not in Kansas anymore.
