My husband and I have only been on one cruise and one river boat (not Viking) and decided river boating was the BEST.....don't have the crowds (only 160 on our boat) and can see scenery on both sides of the ship. (Not so much water). Read reviews on Viking and decided to try.
The crew on Viking Baldur (Grand European - Amsterdam to Budapest) was amazing. We had never been on a trip (and we've been all over Europe) that the crew was SO attentive to detail. It was so interesting that many crew members 'wore several hats' and they helped each other. GREAT TEAM WORK, from meeting us at the airport to shuttling us back!!!!!
Our room was cleaned and straightened up several times a day. On each venture out, bottles of water were given out, umbrellas were available...if it rained (only had one slightly rainy day for a couple hours), and the crew always welcomed us back with a cool drink.
Very adequate!!!!! We didn't spend much time in it except to sleep because we were so busy all day!!!!!!
