I sometimes travel as a Dance Host aboard Silver Sea, Cunard and Holland America ships. This gives me the opportunity to leave winter in Maine for stretches of a month or more without breaking the bank!  So far I have been to 49 countries.  I have become an expert at hitting a port and figuring out how to see what is there on a shoestring.  Sometimes my onboard account after a month of cruising is as low as $4.00!
