If.....and its a BIG "IF" Richie was back for the 2020 Bon Jovi Cruise, it would make it a lot harder for him not so show up for "Personal Reasons" whislt out on the sea....The captain would have to sit at Jon's Table!!! and not the other way round.
Just think about the moneyspinning oppourtunities the CEO and Matt could dream up with each level of cabin. GOLD CIRCLE standing plus your own porthole in your cabin, dine on Matts' Wifes cousins brothers table with a free bottle of exclusive BON JOVI wine (the stuff they didnt knock out over the last decade).

The list is endless and sounds like a huge entrapment to lever every last drop of cash from your pocket. Once your on the ship your just a cash cow for the Bands management machine. I personally would hope that the CEO would think better of it.
