Positives: The Pearl Mist is a wonderful ship - comfortable and clean. Ship's staff in dining room and elsewhere were professional and courteous. Meals were fabulous. Night-time entertainment was excellent for such a small ship.
Negatives: The itinerary was completely different from what was advertised. Scheduled stops were arbitrarily changed to lesser known venues. Planning of stops was poor - passengers were basically left on their own to figure things out. No respect for many of the elderly people during shore visits. It was clear to the passengers that the ship's stabilizers were not functioning as they should - resulting in a change of course from Panama to Colombia, and a one day premature arrival in Cartagena.
Worst aspect of the cruise: The Pearl Seas Cruises company representative (John) did a very poor job. He was aggressive and confrontational to several passengers, raised his voice when asked simple questions, and was intimidating to passengers who asked reasonable questions about the arbitrary itinerary changes.
