As the first Quantum Ultra ship, 2019's Spectrum of the Seas, under construction at Neptun Werft/Meyer Werft, will have a few changes. Some of those are beginning to trickle out.

One main restaurant

Instead of the four main dining rooms—Silk, American Icon, The Grande and Chic—Spectrum of the Seas will have one main restaurant with a grand staircase, according to Michael Bayley, president and CEO, Royal Caribbean International.

Ultimate Family Suite

In another change, a suites neighborhood is being created, he said.

Spectrum of the Seas will also offer an Ultimate Family Suite, which has just debuted on the new Oasis-class ship, Symphony of the Seas.

On Spectrum, the Ultimate Family Suite will be a bit wider, along with some other tweaks, according to Laura Hodges, VP guest experience.

Bungee trampoline VR experience

And the ship will have a Sky Pad, the bungee trampoline virtual reality experience that's being added to Independence of the Seas and Mariner of the Seas. Having tested Sky Pad, Bayley called it 'the bizarrest, most surreal experience you'll probably have.'

Spectrum to replace Quantum in Shanghai

After Spectrum of the Seas is delivered in April 2019, it will head to China, replacing Quantum of the Seas in Shanghai in June. Quantum is moving to Tiajian for the summer, then, starting in November it will redeploy for a just-announced six-month season sailing in Southeast Asia from Singapore.

Spectrum follows 2014's Quantum of the Seas, 2015's Anthem of the Seas and 2016's Ovation of the Seas. Upon its introduction, Ovation also went directly into the China market, and has sailed seasonally in Australia/New Zealand and Southeast Asia. Ovation will be redeploying to Alaska in 2019, becoming the first Quantum-class ship to sail on the US West Coast.
