From the start:
1. Corinthian Hotel, Prague - quite a distance from city center, old bed with springs coming though, price for 2-night extension through Viking was $399 per person, price per room through hotel was $100 per night, rude employees, kept requesting toilet paper but ultimately had to take from public WC in lobby.
2. Ship - Booked a balcony room and when our luggage was brought to the room the attendant told us to make sure we didn't open the doors to the balcony because it would let in all the spiders. On two occasions, the ship did not dock were it was supposed to dock and on one occasion we were tied up to another Viking ship whereby our balcony was connected to a french balcony on the other ship which blocked all sunlight during daylight hours. All night, heard voices and the ships rubbing together. Additionally, the river had 44 locks (which was never divulged in any cruise docs) whereby the entire view was a concrete wall which the ship constantly bumped. The sun deck was closed for almost the entirety of the cruise. Food was terrible. One night there was a semi-coiled wire with a sharp edge in the onion soup.
3. Excursions - included excursions required extreme, long walking distances and are not suitable for people with ANY mobility issues. Some tour guides were rude, especially a guide in Cochem that yelled at a traveler that she was too slow and he would not let her continue on the castle tour and town tour. He embarrassed this person so much she was literally in tears.
4. Transport from ship to Paris - Required sitting on a cramped bus for 10 hours. Made a stop in Luxembourg, but again not at the scheduled stop, creating a very long walk to town. The bus would not allow anyone to stay on, so a passenger was forced to sit on a bench at the bus stop for more than 2 1/2 hours because she was unable to walk the more than a mile distance into town. Bus driver further caused complications when he unnecessarily parked as far away as possible from rest stops, etc. Total lack of consideration.
5. Paris - beautiful city, but the hotel Viking uses is lacking. Our view from our room was the loading dock for the hotel.
Viking's lack of respect for passengers was shocking. They are not upfront in their advertising. They are overpriced, overrated and insensitive. Viking may be the most advertised river cruise company, but it is certainly not the best. Also note, there really isn't any entertainment or activities on board, so if you have any mobility issues that preclude you from walking more than a mile or two, your trip will be a very boring experience. I would never sail Viking again.
Typical small cabin - nothing special, nothing horrible, except we were warned not to open the balcony doors because of the spiders.
