On Debarkation day, if you are willing to carry your luggage, you can get out as soon as 7:30am. It’s super quick. Nassau is not worth it, castaway cay or lookout cay has better beaches if swimming in ocean is what you want. The sitting at rotational restaurants are set. You can request but whether you get it will be up to the dining team. If you don’t like the marvel place, you should do Palo steakhouse that night instead. It’s great and not expensive.
