We had not sailed on a giant ship previously, so this was a new experience for us.
Yes, the ship is bigger, which means more walking and larger crowds at the buffet, but the larger ship means they are able to put on more professional entertainment and a larger assortment of other activities.
We were a party of 12, and all of our cabins were very nicely designed and maintained by the cabin staff.
Best cabin layout I have ever had on any cruise ship. Really nicely laid out, with lots of storage. The bathroom shower stall seemed larger than most.
We walked down the pier and into town for some shopping, then back to the boat
