I cruised with DW and another couple on Summit June 1 and I was a little nervous because of the remarks I heard on CC reviews. Keeping it short, here are a few points:
Got the champagne while boarding - some folks say that they missed it. Bayonne is still an odd embarkation: You get your sea pass then board a bus to get to the ship a hundred yards or so away. You board on the lowest deck, rather than going up a ramp to Deck 5 like in Ft. Lauderdale. This creates a bottleneck, but being on a cruise, I'll take it.
We had the Classic package as part of the 123 Go offer. Not sure if I could ever sail without one again! Contrary to what we heard, we were always served promptly and courteously. In Main Dining, our wine steward was prompt and attentive. She always recommended a pairing that fit in the package and never made us feel bad for not buying bottles. Throughout the ship, there was plenty to drink. If I was on S class, I might have felt sad not getting unlimited Molecular Bar drinks, but Summit doesn't have one, and I can skip sweet martinis. I drank a lot of Heineken Lights and I liked the Dark & Stormy. And wine at dinner. And club sodas, water bottles, and specialty coffees.
The Concierge class cabin was comfy with a slightly larger balcony, but I didn't need the other amenities. But the up charge was pretty small.The location was good, and there was little noise.
