I like how you talked about people can get paid from steem doing what they're already doing, that's sure to get some attention from staff and customers alike. They can gain so much from coming into this while steemit is still not mainstream at this point. Examples include:

Post regularly using their own tag and delegate SP to frequent verifiable posters, incentivizing customers to show how "exhilarating the cruise is!"

Create their own steem smart media token to have customers purchase amenities, thereby locking them into their own ecosystem

Showing reviews are made by real people due to the verification process and reputation score, giving authenticity to the experience they want to convey

I bet if you show them that list, it'll make them change their tune really quick.
