The problem with a large cruise ship is that it usually berths at uninteresting container terminals a long way from the excitement of the port and the passengers are transported by shuttle bus.The ship run bus tours to Bangkok included a 4 hour return bus ride-so we opted for the shorter free shuttle to Pattaya beach.
The only port we berthed close to the city.We took a tram ride to Peace Park and the Atomic Bomb museum which was very moving.Not many passengers returning to the ship with purchases here.
Busan rated 4....quite interesting especially the fish markets
Beijing rated 5...the end of our cruise and a very interesting place to visit. the ship berthed at Xingang 140 kilometers from Beijing and the ships transfer cost by bus was $us80pp.We took a local bus to the town of Nanguu then a train the the town of Tianjin and the Bullet train to Beijing all for a cost of $us16pp
