I posted the trip report of my GCT European River Cruise in 2006 on TripForums. Here is the link:
Castles, Cathedrals, and Cobblestones - TripForums
If there is an easy way to take the thread from that forum and post it here, I have no problem with that. I will be posting the report of my recent trip to Italy as soon as I have time to write it.
