I've had that "natural ecstasy" feeling on a cruise six months ago (my first cruise ever). The first evening, the ship was going through a rough patch. The were a lot of strong winds and choppy waves. Several hours into my cruise, after I unpacked and ate lunch, I downed a strong drink and went to hot tubs at the aft end of the ship, and enjoyed the view and the bliss I felt, while the ocean rocked the ship strongly enough to splash the water out of the hot tubs. The audible rumble of the thrusters and the whooshing of the wakes behind the ship drowned out most of the noise from people talking. I was in heaven, knowing that my cruise was just beginning and there were days of endless fun up ahead; heck, I haven't even gone to my first dinner yet, which was supposed to be really good.
