Four of us sailed on the Emerald Sky from Aug 10 to Aug 24. We got on the ship in Budapest, and disembarked in Amsterdam.
We had Emerald make the air bookings and airport to ship and ship to airport transfers. Our travel agent was able to include the Premium Alcohol Package (I think that is what they call it), which gave us free, unlimited drinks. The only exception was upgraded wines and champagne, which costs extra.
Emerald has "included" tours at every port. They also had "Discover More" tours that cost extra at some of the ports. Two of us took in the special Vienna concert and one of them took the special tour to Rothenberg. The only other extras we paid for were a couple of laundry loads (24 euros for washing and ironing for a medium size bag of clothes).
