What travelers are saying

"UnCruise is an amazing dream!! The crew, the sales team, the office team, all go out of their way to make sure your experience is unforgettable. We were on the August 1, 2020 cruise. Even tho things didn’t go quite the way we planned, UnCruise was unbelievable. We will be back. UnCruise was my first ever cruise. They will be the only company we ever cruise with."

What travelers are saying

"We had a really terrible 10 days aboard the Glen Etive. They are short staffed so used temporary and inexperienced staff. The customer care was poor, cabins not cleaned, boat broke down, we did not get to the outer Hebrides- instead travelling up and down the Scottish coast. We felt unsafe on the tender - receiving help from the RNLI on one occasion. We hardly slept on the hard beds. Overall. Would not recommend to anyone"
