Business cruises are the place to combine work and pleasure. Who ever said that the two could never meet? That person has clearly never been on a business cruise. People use business cruises for a whole variety of reasons. You could have a corporate meeting on a cruise.
It's a nice place to have a meeting and you could do it in a really relaxed atmosphere to signify a special occasion, or just as a way to meet all of the senior staff and partners' children and spouses. This can help bring businesses closer together and can aid swift decision making people will after all want to get to the pool. You could also use the cruise for a business reason but leave all the business on the sure. As the boss of a company you may enjoy cruising yourself.
As a treat to your executives you could offer to pay for them and their families to come on a business retreat. If you work in a fairly relaxed company this can be an excellent for everyone in the business to get to know each other better in a more informal setting where blue thinking can actually happen between the blue sky above, and the blue seas below. Holding a conference on a cruise ship is another sure fire way to ensure that you firstly get a lot of people on the cruise since it's a holiday for their families too and secondly as a way of ensuring that you enjoy whatever the conference subject is. They are of course much more likely to engage with it if it is held somewhere other than a miserable hotel where all there is to do is drink at the bar or sit in your room waiting for the next day's activities.
It couldn't be anymore different on a cruise there you allow people to do many activities, to eat delicious food, and to be able to really engage with the subject matter of the conference in a way that just isn't possible otherwise. Cruise ships are especially good for conference and meetings that need to be kept quiet. The conferences on cruise ships can of course provide much better security than a normal conference.
You won't have anyone sneaking in through a back exit on a cruise ship. And the privacy of the event will be guaranteed, as will the identity of those involved.
