This was our third Uniworld cruise so we had two others to compare. As with the others, we thoroughly enjoyed this cruise. That is not to say there weren't a few negatives which I will get to later. My comments are intended to be constructive and I would not want to let them dissuade you from taking this cruise.
First though, I need to acknowledge the exemplary crew. They were always at the ready to happily do whatever was requested. They are very personable and go out of their way to make sure you aren't lacking for anything. Even up to the Captain who joined us for a drink and a bike ride (on separate occasions). Nobody knew each other before the cruise but we soon formed a group of ten. Being part of such a group goes a long way to making the cruise that much more fun and enjoyable. I would encourage anyone to quickly make some friendships rather than go it alone as a couple.
Food was always very good. Presentation and service was excellent unless, of course, you opted for the buffet (breakfast and lunch) then you know who to blame. There is a fixed menu for the Captain's Welcome and Farewell dinners. We can't agree with the few criticisms regarding lack of choice as the meals were top notch. Maybe those with a food restriction of some sort could possibly find it less than ideal.
Even though the Po River had dried out and we were 'confined' to the Venetian Lagoon, we did not feel we missed out on too much. Only one day was impacted when we had a longer bus ride to Bologna than what would have otherwise been the case.
Being all inclusive is the way to go. You are not forever signing charge slips, paying for tours and/or handing out tips as on an ocean cruise. The decision becomes which tour shall we go on rather than how much is it going to cost us. "Front of the line" and/or exclusive openings is terrific - no mobs and long lines to have to tolerate.
The local tour guides were impressively knowledgeable, maybe to a fault. Sometimes we felt a little overwhelmed by long history lessons - but there is so more than what we have in North America. It may well be a case of what is too much for some is too little for others - damned if you do and damned if you don't. The guides' English vocabulary was really good and I was often surprised at some of the words I wouldn't have expected from someone using a foreign language. But they all seemed to have been trained at the same school where they learned our words properly should have an extra vowel tacked on the end. Something like "Nowa, let'sa walka this waya" or "Crossa over the bridgea". I'm not being critical as it got to be somewhat humorous at times. I guess it's a part of the Italian DNA.
Admittedly, we didn't get the book out and compare square footage. But the cabin gave us a sense that it was smaller than, for instance, the same cabin on the River Princess. Maybe, the positioning of the bathroom door was a factor. Someone could easily lose a knee cap if s/he was sitting on the edge of the bed and the other person unknowingly came out of the bathroom too quickly. Having said that, the cabins are very well appointed and clean. The fairies who come into your cabin when you aren't there to make your bed, etc., do an excellent job.
The big negative? The horrible internet service (and I use the term 'service' loosely). More often than not there was intermittent service or none at all - even if the ship had been tied up all day. Then, if and when you could get access, it was very slow - reminiscent of the old dial-up days. More than once I encountered a service drop in the middle of my trying to do something.
A relatively minor point: I'm not sure if it was the particular driver at fault or the schedule. The long drive from Milan to Venice was very slow. It was very unusual for us pass another vehicle - they all passed us. The other bus with us had long disappeared out of sight. If it was a scheduling matter, I don't think it is necessary to leave Milan quite so early.
We opted to not do the Rome extension.
