Talk to any cruiser, and they’ll tell you their biggest pet peeve is nickel-and-diming. (Wait, we have to pay extra for a shuttle into town? And yoga?) Fortunately, there are tons of things on every cruise line that you don’t have to pay extra for, including on budget-friendly Carnival Cruise Line’s ships. So, even when the fare drops — and sometimes they go way down — these treats will always be included in the rate.
