My wife and I are avid cruisers. We are in our 60's. We are now huge fans of Virgin Voyages having completed 7 VV cruises so far. We dont party, but really enjoy the attitude of the staff, and the friendliness of passengers. There isn't an expectation of dress, but it just feels "comfortable" on board. Some have mentioned the larger size "yacht" feel- which I agree with.
I think is some of the very best food we have ever found on a cruise ship. It's well thought out and prepared. Personally, I am looking forward to a bit more variety in the Galley, but I have to believe it will come.
