I'm not going to review Ronjo as if I was expecting the Burj Al Arab - I appreciate the place is in the middle of nowhere. However they charge a fairly sizable sum for the accommodation, and I think that some aspects could be improved.
There is no running water in the tents - you get 10 litres of lukewarm water per person to shower with, made available when the staff decide to fill your tank attached to the back of your tent - at around 7pm. Staff bring a bucket of water each morning for washing purposes. This bucket isn't left outside your tent (which surely would be quite straightforward to arrange), but is instead brought right into your tent, at 7am, by a chap striding past your bed shouting "HELLO, HELLO". Quite a bracing way to be woken up if you're not expecting it.
There is a proper toilet in the tent, but the water is exhausted after about 3 flushes. I will leave the potential consequences of this to your imagination, but it's not great if you happen to have any form of diarrhoea.
You will also have dinner when the staff specify - we ate at 7.30pm one night, 7pm the other. Food is adequate, and served in a large tent with both sides unzipped. Breakfast is served in the same tent and degenerates into a stressful exercise in constantly swiping at flying insects - while al fresco dining is idyllic, the staff should really consider whether offering a closed tent (similar to the bedrooms) may be more realistic.
Lastly you will hear a LOT of strange noises during the night, including animals shuffling around right outside your tent. It's terrifying at the time, but quite cool to look back on afterwards.
