We had planned for our first trip to Europe in almost 30 years and had been sold on the Uniworld Castles on the Rhine river cruise by Uniworld reps. When we arrived in Basel the captain and cruise director allowed all passengers to board. We were unsuspecting of any issues, but Uniworld KNEW that the Rhine River was IMPASSABLE and they boarded everyone anyway. Then 24 hours after boarding at the first night Captain's dinner we were informed that the river was impassable and our river cruise was OVER. We would reach our first stop, Strasbourg, and that would be it for our boutique, high quality river cruise. Uniworld knew about the river levels BEFORE and still allowed all passengers to board. No amount of rain would have changed the outcome!! Passengers should have been informed before boarding and given an option of a refund. A cancellation would have been a huge disappointment, but fair. Once on board we were basically their CAPTIVES and spent the remaining time crammed into buses for hours, lugged our own bags around from location to location, stopped at gas stations to pee, and were given a meager amount for daily meals. We sat on a speeding bus for our Castles tour seeing more buildings and phone poles than castles. The staff seemed overwhelmed,frus trated, and unable to help. Our days were poorly organized, and attempts to contact Uniworld's customer service went unanswered. Every day, rather than relaxing on the cruise ship, we had to find our own restaurants for meals in unknown destinations with inadquate funds for the exquisite meals we had paid for. We arrived one day early in Amsterdam after hours on the bus and were put up at the AIRPORT hotel with a lovely (sarcasm) view of the control tower. We had planned to stay in Amsterdam for two additional days and had selected our hotel to be near our final destination. We now had to travel from the airport to our hotel on our own, at our expense with no assistance from the staff. A $1,000 per night boutique river cruise it was not!! The entire experience was a fiasco and very poorly handled by Uniworld! We ended our boutique river cruise experience frustrated, exhausted, and stressed. We were offered a $1,000 credit for a future river cruise expiring in 2019. That offer had no value to anyone!! The company intentially boarded passengers so they could make their profit. They put corporate PROFIT over honor and customer service! We are beyond disappointed with our first river cruise and more importantly with how Uniworld handled the difficult situation. I would encourage you NOT to book with Uniworld. Look elsewhere!!
