I was on Zenith for a 14 nighter this spring. Great ship, and a great crew. The crew takes extreme pride in their ship and their service to guests. Excellent chow. You absolutely can't go wrong on Zenith.
Its older, but the crew constantly maintains her. Sure, there are a few worn spots here and there but no more than on any newer vessel.
I prefer the size of Zenith and Century to the Millie class. Your mileage may vary.
We are looking at Zenith for next year to Bermuda. So far we have only been on RCI Grandeur and Monarch. How does her size compare to these? Everyone says she is a smaller ship, and I'm trying to judge what that means. Also, how are the interior staterooms on Zenith? We have had an outside and balcony and are trying to save some money this trip. Thanks for everyone's help.
