First, let me say that the crew of the Avalon Visionary were wonderful. They did everything in their power to make the trip a pleasure, but couldn't overcome the shortcomings of stateroom 202. The continuous sound of running, splashing, gurgling water beneath our cabin floor caused us endless sleepless nights. We would emerge in the morning for breakfast looking like zombies. When exhaustion did bring on sleep, we were frequently awakened green and gasping as diesel exhaust fumes wafted through our cabin courtesy of the air conditioning system. There was no fear of motion sickness on board, but carbon monoxide poisoning was a real possibility. The on-board entertainment system was nice, but only worked sporadically. Then there was the day when our room inexplicably locked us out. This was surely an omen. Only a crew member with a master key could let us in that day until the entire lock system was replaced.
On the final evening of the trip we had a silent tour of Budapest at night when our local guide was given a dead audio transmitter.
Note to beer lovers: The complimentary on-board beer served with dinner is awful. It looks and tastes like....well....you know. After the first night nobody touched the beer. We all switched to wine, which was quite good. Small (0.3L) bottles of German beer were available at the bar but cost 3.5 Euros (about $5). Slake your beer thirst in Prague, where delicious Czech beer cost less than $2 for a half liter. Wish we had brought a case on board.
