We liked the itinerary of this cruise however, the river was low and we were informed at 6pm the previous evening could only board at Passau not Nuremberg. We arrived in Munich Airport at 11am - our baggage did not arrive until 12.15, we could not find the meeting staff for Emerald - no signs - no notices at the cafe proposed for the meeting. We were then approached by a lady with no identification telling us that our transport had left and we would not get transport until 14.30 - flippantly told just to have some lunch!! We were taken to the car and left the airport at 2.30pm. When nearing Passau the driver informed us that we still had one hour to drive. He then proceeded south and obviously had no idea where he was going, we went through fields and farmyards but no sign of a river. The driver would not stop to find out where we were - my husband called Emerald Dawn and asked where they were berthed - he told us near the central station in Amsterdam! After a further 4 calls where the driver would not communicate with the ship - we asked for his papers which stated we were going to Emerald Sun. We finally arrived at the ship at 6.20pm - no apology for lack of information or inconvenience, in fact quite the opposite. We wrote a letter to the CEO of Emerald and handed a copy to the cruise director - he did not even acknowledge it. They then told us we would be going back up the river to Regensburg the following day by coach - 2.5 hours each way - this was not what we expected and could not face another long bus trip. By the next day we had somewhat calmed down and the remainder of the cruise was good. On leaving the ship on 15th Sept. we were taken to Budapest Airport for the flight to Amsterdam and on to Edinburgh, the flight arrived late - the air bridge would not work the steward announced we would still catch our flight to Edinburgh. We RAN to the gate to find out the Edinburgh flight was gone -we are 74 years old and did not feel good after this rush. KLM were very helpful put us on the next flight where we found that 2 of our fellow ship passengers going to Edinburgh were booked and had not had the rush to a flight that was gone. The inefficiencies of the transfers were appalling, but the most disappointing was the attitude of the management of the ship, they were just not interested. this experience would not entice us to book Emerald again, in fact we could not recommend it.
