Cruisemates Group Cruises are available to anyone, regardless if they are registered on the site or not. Of course we'd like them to register.
The only requirement is that you book the cruise with the travel agent handling the cruise in order to receive the pricing and the amenities. Once you book you can either participate in the group activities or be on your own. You can also do a combination of both. That's the great part of the Cruisemates cruise. You can do what you like.
You can arrange a wedding, or renewal of vows on the cruise. You can arrange this through the travel agent or through the cruise line.
Take care and I hope to see you on a future Cruisemates Cruise.
