I am curious to hear how you are enjoying VV so far, if you have boarded already. I did the French Daze and Ibiza Night with my gay BFF (since my wife couldn't come) - we are 47 and 54. We stayed in a Brilliant Suite since that has a sofa that can be made up into a separate bed. I think going Rock Star is going to be key for quiet, early to bed types since you have access to Richard's Rooftop and a calmer vibe on top of the ship. I also loved being able to order room service without any additional charge - fresh fruit and pastries to your room in the morning may suit you better than the considerably noisy galley for breakfast. You will probably have trouble drinking all the alcohol that comes with the room, in addition to the bar tab (I know we did).
One of my fave things about VV was the inclusive vibe on the ship, being welcomed by the very diverse and fun "happenings" cast on embarkation and seeing them all around the ship, eating where we did, etc. The Rockstar agent was very helpful making any reservations we wanted and changing anything, etc but it was not English Butler service if that's what you are used to on other lines.
I will say that traveling with my BFF and a large gay group meant that I left my early to bed, early gym workout days behind me for a week and stayed up late for meals at 9am and the big parties afterward. That was fun but also wore me out and I am looking forward to a quieter cruise with my wife next year. I wanted to maybe try one of the VV Greek ones but it was sold out for the dates we wanted. Although we attended nearly all of the parties, I also met people on the ship who went for earlier meals and entertainment and seemed to really enjoy their cruise without going to the late night parties. We did some of the group workouts but I would have liked to spend more time in the gym. I am really interested in hearing about your experiences on VV, given your background with other cruise lines and smaller ships.
