This would have been a wonderful cruise had it not been for the groups of people who came on board for purposes other than enjoying an architecture cruise. One group was there to have a casual business meeting in a pleasant environment and the 10 of them carried on conversations both inside and later outside the cabin for the entire length of the cruise. They were impossible to escape. Another group partied loudly outside and so it was impossible to concentrate on the architect's descriptions or find a quiet spot away from constant gabbing. I asked an employee to remind them to be respectful of paying guests after the docent architect had done so himself. She smiled but did nothing. I spoke to her again at end only to receive another smile. I spoke to the architect and he said that after his first time asking guests to be considerate, it was up to the crew. Such a shame. The experience could have been so enjoyable, but I would not recommend this to anyone who really has an interest in architecture. It is pleasant if you just want to party and see the sights.
