Interesting thread.
Many of your comments made us so happy that we cancelled FJORDS last year.
Amongst our favorite cruises:
1999 Baltics on Diamond (our first cruise ever)
2001 Rome to Istanbul on Diamond (right after 9/11 so only about 125 on board)
2003 VOF (where we met many of you for the first time)
Least favorites:
MUSH - I guess we're not really nature people but had a nice time with LCTers and got Alaska off the list
2002 - Song Lisbon to Nice (got seasick - bad cabin etc. - even though one of the stops was Gibraltar)
We just got back from a riverboat cruise on the Rhone & Saone rivers in France (Marseille/Arles up to Chalon/Paris). Definitely not as good at the Danube (Prage to Budapest in 2005 was). Kind of sad when the highlight of the trip was the hotel post-cruise (we got a huge upgrade on an award points stay to a huge 1 BR suite which would sell for over $2,000 a night at the Park Hyatt Paris on a night when they were sold out with dignitaries including the Spanish, Greek, Polish & Luxembourg Presidents/Prime Ministers attending the Paris Summit - see http://www.flickr.com/photos/45305718@N00/sets/72157606190684238/ for pictures).
