@AimeChambers The internet is your friend Aime. Cruise amenities and activities. A cruise is basically a hotel/massive entertainment place. With a pool, Spa, Sauna with a view, Jacuzzi, live theater, movie theater, "Movies Under the Stars" while you swim, Dance Club, Casino, Bars and Lounges, massive eating area with Starbucks, Fitness center, Arcade, basketball court, ... etc
It depends on how fancy we get. Royal Princess is one hell of a fanciful cruise and then there's the Carnival cruise to work from too which has an IMAX theater, Sky ride, Comedy clubs, Serenty retreat, Sea park, Game shows, Candy store, shops/stores to waste all your money at, art exibits, karaoke, Mini golf...
LETS JUST SAY THERE'S A LOT OF THINGS YOU CAN PUT ON A CRUISE, so I suggest basing everything on an actual cruise. You'll have to name the bars, lounges, different areas because cruises don't have generic names. They name each area specifically to make their cruise special. For example: Alchemy Bar, Vista Lounge, Club 6, Princess Casino...
so yeah. The names don't have to be amazing but they will help your roleplayers out. Deciding on the destination is the easy part, but creating the actual cruise experience will take some time and work. Just gotta do your research.
Since you're the gm, I will help point you in a direction but I don't have time to actually make the roleplay with you. Research on the web, it'll do you wonders.
