Our hotel in Monaco was situated right on the Marina and even though we were on the ground floor we had an outdoor terrace which looked straight out onto the Marina and these gigantic sparkling yachts.  They were quite a sight.  It was mostly crew onboard and at night it seemed to be a backpacker who had the job of minding the yacht and keeping the lights on etc.  Not a bad job at all.
