Hi, I'm so sorry you had such a rough time on the Valor! Really sounds dreadful. We're mainly HAL cruisers but went on 2 Carnival cruises last year (Panorama to Mexico with family inc. kids and Sprit r/t Alaska from Seattle just the 2 of us for a cheap and quick anniversary adventure). Just our experience, we'd do the Panorama again if family wanted to go, but it wasn't really our cup o' tea......big ship, overbooked, lots of kids, etc. Buffet was scary. Still, fun with the family, and the kids had a ball! But the Spirit? We really weren't expecting much ..............and we had a WONDERFUL time. The food wasn't outstanding but it was tasty and mostly well prepared, our balcony cabin was great, staffing was good and the ship was lovely. We went to the Steakhouse twice and really enjoyed that, hit up the sushi restaurant the first night and pretty much had the place to ourselves, very good. We pretty much did our own thing and didn't mingle a lot, so had no issues with other passengers.
I just want to say that we really hope your next cruise is a good one, and that you enjoy the Spirit if you decide to partake of that sailing! Best wishes and safe travels!
