We are experienced cruisers, but had never tried Seabourn due to their smoking policy on verandas, but we liked the Montreal to Boston itinerary and decided we would take a chance.
We arrived at the ship around 11:30 am and waited 30 minutes or so before they started check-in. By that time there were a number of passengers there, so there was a line for check-in, but it went relatively well. We were told that the cabins were not ready, so we had to carry around our carry-on bags for a couple hours. We later learned that there was a place to check bags, but Seaborn did not provide information on this.
Overall the food, service and cabin were exceptional, the best of any ship we had ever been on. We mostly ate dinner in The Restaurant, where we had outstanding service from Guillermo. We also enjoyed Restaurant 2 very much, but could not eat there but once as they quickly booked up for the entire cruise. We ate one night at the Colonnade, which is the buffet area but provides "sit down" table cloth service most nights. Food there was good and although the service was good, it was not nearly as good as the other two dining venues.
