Nothing beats relaxing by a pool with a nice drink in hand as you feel the fresh sea breeze pass by you. The problem is that with thousands of people on a ship, there's not always room. If you want to spend all day for 7 days in a pool, a cruise isn't for you. You would have a much better bet choosing a resort with a huge pool complex. That being said, a quick dip in the pool can be nice on a hot day.

The Royal Caribbean Mariner of the Seas has a total of 3 pools and 5 hot tubs. Tired of loud kids and splashing? 1 of the pools and 2 of the hot tubs are adults only.

The Royal Caribbean Harmony of the Seas has the same number of pools as the Mariner of the Seas and more hot tubs.

Cruise Costs

Royal Caribbean is a mainstream cruise line. Mainstream cruise lines cater to a variety of guests, hoping to provide something for everyone. These typically cost about $100 - $350 per person per day.

Cruise pricing is dynamic and varies for each specific sailing based on factors such as departure point, ports of call, and time of year. Typically newer ships cost more, so a cruise on Royal Caribbean Mariner of the Seas will likely be cheaper than on Royal Caribbean Harmony of the Seas.

Onboard Costs

Another way to gauge the cost of a cruise is to consider how much you'll spend on board. Even though a lot is included in the base cruise fare, you may still spend money on things like spa treatments, specialty dining, drinks, and excursions. In addition, guests can also have to pay for things like gratuities and tips.

Typically guests can expect to spend about 25 - 40% of the cost of the cruise on onboard expenses. In other words, if the cruise fare is $1,000 per person, you might spend between $250 and $400 on extra expenses.
