Heh...I cruise around the pacific on a commercial fishing vessel.They have really good catering! Ravioli in a can under the exhaust manifold!
Flew to Athens then cruised islands in the Aegean till eventually flying back from Instanbul. That was about 15 years ago. Not sure I'd want to do it again in today's political climate.As far as Mexico goes, prepare to be molested incessantly by street vendors and guys pushing time shares. The bit about the water is mostly true. It's probably ok at the larger hotels, but elsewhere beware. One word... cerveza.
