My brother, who had taken previous Viking Ocean cruises, talked me into it because my wife and I had taken several river cruises on Viking and had enjoyed them. The four of us had cruised before and enjoyed each others company.
We very much enjoyed and were impressed with the Amazon River experience.
I would have greatly appreciated wider WI-FI coverage. We had to very frequently rejoin the wi-fi because of lost signal. Perhaps some wi-fi repeaters placed strategically throughout the sip would help.
Abdul, our attendant, was very helpful in several ways.
