This was my second trip to Atsumi, the first was 6 years ago. I lost 13 kg in the lead-up and at the retreat this time (16 last time); my flexibility increased greatly through Yoga (new to me); and generally gained some balance back in life (coming from a workaholic, travel, business dinner & drinking environment). It was a great way to hit life's "reset button".
All but one were return guests (one had been there 6 times). It's small, low key, and friendly. A new person showed up every day or two, and people left on the same pace. My group included a few Canadians, a few Aussies, an HK born SG resident, a gal from HK, a French Dubai resident, a Brit and me (American). All were nice and interesting people. You also get to know the great Thai staff well (+ a German & Canadian, and a few others). You can spend the day doing activities (yoga, colonics, massages, beach trips, night market, etc.), or you could opt-out and chill out. My favorites - Orlando's Yoga & Moo's kick boxing (others were good as well). I was also surprised to find an 8 day full fast is not that hard!
I plan to go back every 2-3 years. You an find posher retreats, but this one has the "secret sauce".
