us go without someone 25+? My friend and I are looking to go on a cruise to celebrate our 20th birthdays since they both fall in the same week. Everyone I have spoken to has said you need to be at least 25. I know Disney Cruise Line allows 18+ but were not really looking for a Disney Cruise, we were thinking more like Punta Cana, Bahamas, Jamaica, somewhere like that. Do you know of any Cruise Lines that allow both persons to be 18+?
