You seem to have a track record of unhappy experience in Kenyan lodges ... from what you've posted on FT. If you decide to stay in a lodge in a country where water is a scarse commodity it's only responsible to conservie it.
If you want to indulge in water use, perhaps you should consider staying somewhere where water is more plentiful ... and that probably means in a city in Kenya.
To avoid disappointment in future, might I suggest you research the country and area you are visiting more thoroughly before you visit. You don't say where you come from, but most of the 'civilised world' can learn from other societies and cultures ... and accept that this means seeing things we're used to in a different light and being able to act accordingly.
