The crew was hard working and friendly. Unfortunately, the Orbridge "Expedition Leader" was a very poor leader--he had some knowledge, but clearly was 'mailing it in.' He cared little for the passengers and made no attempt to get to know anyone's name or anything about the passengers. Often he was sarcastic in answers to questions to which he did not know the answer. The boat was nice, but the bathrooms were filthy and often smelled--the toilets visibly had not been cleaned for months. The sewage pump did not work, and thus one-half day of activities was eliminated because the captain had to get to Sitka as soon as possible. This was my first cruise and I was surprised there was so little information from the Expedition Leader and the captain about the problems the vessel was experiencing. At no time did any member of the crew wear a mask--not the servers, the cook or the bartender, who was diagnosed with COVID several days into the trip. Although the bartender was living in the crew's close quarters, not one crew member wore a mask after this illness was discovered: there were rumors he had COVID, but this was not acknowledged until we finally directly confronted the Expedition Leader and captain. Clearly, they were trying to keep this information from the passengers, in my opinion. I will never travel with Alaskan Dream Cruisers or with Orbridge in the future, and neither will anyone of the folks aboard with whom I spoke about these issues.
