I have been on 4 VRCs. The "panorama tours" are usually in the big cities to give you an overview. Most of the included tours are to the sites you want to see, with preferred access, for example, The Forbidden City & Great Wall in China; Monet's Gardens & Normandy in France; all the Pyramids, temples, tombs & museum in Egypt; The Catherine Palace, Kremlin, Ballet, Hermitage in Russia. I have taken a few optionals like the dawn hot-air balloon ride over the Valley of the Kings, and Abu SImbal because I REALLY wanted to do them. Well worth it! I like Viking for river cruising, but I'm considering O for Alaska, and Med. for 2020. I think VO is overpriced, but still comparing.
