We are two adults and booked the Icon of the Seas. We feel that the ship has many options for adults only. Yes, the ship will attract many families, but on all ships, we find quiet spots and enjoy seeing families have a great time. My only negative comment is the pricing is crazy, but it is still high for some of the old "tug" boats Royal still has. Thus far, the only ship that have disappointed us on Royal was the Adventure of the Seas. We have tried the Quantum and found that class of ship disappointing. Thus far our favorite class is the Oasis class.
