With just seven cabin categories, the 1,070-passenger Crystal Serenity is more manageable than mega ships when it comes to cabin selection. Each of the 623 staterooms on the all-inclusive luxury ship has an ocean view (85 percent have balconies), and in the upper price tiers passengers enjoy perks comparable to lavish five-star hotels. Ready to set sail on Crystal Serenity?
