Just a thought... are there any hotels who cater to cruisers and host a cocktail party the night before sail away? Sort of like a meet and greet? Seems like it would be a good way to lure business if you are nearby a port.
Offer airport shuttle and port shuttle.
Special parking and stay prices.
Free cocktail at meet and greet(which they could even do in a bar nearby if they don't have one on site).
Lots of potential customers every week and maybe build a cult following.
(if anyone owns a hotel feel free to steal my idea just invite me for a free weekend lol)
