We've sailed on two other Viking ocean ships, so we expected to enjoy ourselves. We did.
The route through Caribbean islands and up the Amazon was new territory for us.
Because of air schedule we didn't have time to see San Juan, but had a good excursion into El Junque rain forest.
I've never before appreciated what good design can do. The cabins aren't large, but plenty large enough. They feel large. Everything fit together so well, with room for everything. And a very attractive room at that.
The "nature walk" was a little disappointing, too crowded. The guide was good.
