Treated like royalty. Plane ride - Helicopter - Bar 10, great fellow travelers, Great food! Beautiful night skies - milky way, constellations. What better experience could anyone have. Warm, but I'm from the South. Older and retired. A little (a lot?) out of shape - didn't matter - I was taken care of. If anyone has a hesitation, get over it. GO FOR IT. You won't regret it and will come back with a sense of accomplishment and awe.
