The Amadeus Royal is a mid-sized riverboat that has been kept in amazing shape. Everything was clean, recently painted and the crew was very attentive and fun to be around. The ship holds approximately 120 passengers and has a crew of 40. She has a 1.4 meter draft and was able to make it up river to Passau when the larger boats (1.6 meter draft boats) had to turn back or transfer to a smaller boat. The only port we could not make to was Regensburg and Lueftner Cruises chartered a bus and bused us upriver (1.5 hours) and bought us lunch.
The Amadeus Royal is available for charter and the tour group we were with, chartered the entire boat, so the tour company (Alki Tours) took care of all shore side activities (and did a great job!).
The weather was perfect so most people spent a lot of time topside. But during evening the lounge could accommodate all 120 of us but it was a bit crowded.
