My parents stayed at Knutsens and Willis in Huntington for 25 years. I don't know if things have changed but they enjoyed the life so much I want to do the same. As far as water, it was a challenge they managed. Join a gym, work out a little bit and use their shower. It won't hurt I promise. They make incinerating heads that use very little water, and there are water desalinators, although they are far from perfect. If it's what you want to do, you will make it work, if not it will be a chore beyond comprehension.
