I'm concerned about the bits I've read about the explosive issues with heating water, but I'm sure it must be doable especially as I've seen hot tubs heated by thermo syphoning.
Please can someone suggest a good way to heat water that is safe (and possibly fun) for campers to use.
You can buy shower bags that you can hand from a tree which have the shower head integrated into the bag.
Personally when we are camping out in our own woods we have a fire running pretty much all the time, and it usually has a big kettle on it for brews.
Outdoor showers are lovely, but you want a bit of screening for privacy and some kind of floor so you don't end up showering in mud. 4 pallets placed in a square works well as a floor (maybe hit them with a sander to get rid of the worst of the splinters!).
When I used outdoor showers in a group setting the shower space was 100m or so away from the camping area (privacy through distance) and was in a natural thicket of yew bushes for decent screening. Simple way to prevent embarrassing meetings at the shower is to only have one shower bag which you take from the central fire to the shower spot when you need it. Bring it back when you are done. If the bag is missing you know someone is showering.
NB: you might be able to use a solar shower bag with hot water from a kettle, but they seem to all have narrow necks for filling. The one I have used was more like an open top bag so you could pour a bucket or a kettle straight in.

People will be staying in a yurt and our vision is to give them the experience of off grid living, but making it easy. I would like to find away of heating water in a tank by thermal syphon so the water is available through a traditional shower.
Tracy, I get what you are saying, however the hot water is mixed with cold at ground level to get the temperature right. They are very easy to manage really.
We purchased the container new then simply added a low flow head with a shut-off valve. I opted for a metal container so I could have in powdered coated black so in the summer we could just place it in the sun to heat the water. Right now we boil 1 part water then dilute with 2 parts cold water for a 2 gallon shower that lasts 7min of constant flow.
With this metal container it could even be placed directly on a fire/burner and heated if your didn't want to mess with transferring water from a kettle to the container.
You can see our setup towards the end (around minute 8 of this video if your interested:
