Cruises · Panama

Hello, We’re going on a 15-night cruise through the Panama Canal from April 18 to May 3, 2019, aboard a Princess ship departing from Los Angeles (California) and arriving in Fort Lauderdale (Florida). The ship will dock in Puerto Vallarta and Huatulco (Mexico); San Juan del Sur (Nicaragua); Puntarenas (Costa Rica); Fuerte Amador (Panama), full transit of the Panama Canal; and Cartagena (Colombia). Has anyone here got any tips for organizing excursions on my own at a lower cost, and what are the absolute must-sees? For staying 2 nights in Los Angeles near the port, do you have any recommendations for hotels or Airbnbs? Thanks in advance. Martine
