The Cruise offered us access to particular countries / towns that we wished to visit. The Emerald Dawn offered the Cabin standard (Grand Balcony Suite) that appealed to us.
A bit of a rocky start. The transport to ship was impossible to locate (for us and others).
A broad range of excursions were offered. Recommend in particular the Skoda Tour ( of Slovakia in Communist times) and the bicycle tour to Durnstein.
