The family suite can sleep up to eight guests, who are also all looked after by their own personal butler.
Symphony of the Seas boasts a total eight decks and has enough room on board to accommodate 8000 people.
The vessel was constructed at a cost of $1.87billion at a shipyard in Saint Nazaire in France.
Along with having 20 restaurants, there will be more than six bars including one where robots rustle up the cocktails.
Other attractions include a zip wire, ice rink, mini golf course, climbing walls, surf simulator and a full-size basketball court.
Moving to the evening, there is a state-of-the-art theatre where Broadway-style shows will entertain guests on a nightly basis.

Symphony of the Seas - which is the 25th ship in Royal Caribbean's fleet - will launch on March 31 and take its first paying passengers in April, kicking off a summer season in the Mediterranean with calls to ports in Spain, France and Italy.
Beginning on November 24, the adventure-packed ship will make Miami, Florida, her year-round home, taking holidaymakers on seven-night Caribbean voyages.
We'll be on board Symphony of the Seas from April 5 to 7 on its pre-inaugural sailing. For an inside look at the ship and all it has to offer, follow us on Instagram, @nzhtravel.
