What affects the price

When you start looking at cruise prices, keep in mind that the total depends on a few moving parts. The cabin category is the biggest factor; choosing a suite or a balcony room will always cost more than an interior stateroom. Timing is just as important, as sailing during school holidays or peak vacation weeks usually increases the fare. Plus, you have to consider whether you want an all-inclusive package that covers drinks and Wi-Fi, or if you prefer to pay for those as you go. We can get you the exact pricing confirmed free on the call.
