Just noticed a destination error on the Uniworld Cruise Package. The package states the River Queen is sailing from Amsterdam to Budapest:

This 12-night package PRICED FOR 2 includes:
12 nights aboard the River Queen in a Category 5 CabinSailing from Amsterdam, The Netherlands to Budapest, Hungary
Yet, when you open up the Itinerary you find out it goes from Amsterdam to Basel or Basel to Amsterdam. The price of approximately $4900 would have been too good to be true to go all the way from Amsterdam to Budapest.
