No but you can eat in one of the other restaurants onboard like Sabatinis - though there is a cover charge for this.
We sailed at 5.00 pm and dinner wasn't till 6.30 pm so it wasn't too bad....if you are not too late boarding you will have time to freshen up and change for dinner prior to sailing.
No, you cannot change for one night. Indeed there will be a queue of people trying to change their dinner times/tables for the rest of the cruise. Join the queue at your peril !!. Enjoy sailaway. Dinner is freeseating and casual dress first night so find cabin, wash and brush, grab a drink and enjoy !!!!!!!!!
We want to enjoy sailaway what time is lifeboat drill when departing from southampton at 5p.
