Azamara Club Cruises passengers will have access to sister line Royal Caribbean International’s new private island collection Perfect Day, the line’s president has confirmed.

Perfect Day at CocoCay, due to open next May, is currently being constructed in The Bahamas and will feature a 13-slide waterpark; the Caribbean’s largest freshwater pool Oasis Lagoon; and a 1,600-foot zip line.

Royal Caribbean plans to build a collection of private islands around the world.

Azamara currently visits Haiti resort Labadee, partly owned by Royal Caribbean, which is also undergoing changes before it joins the Perfect Day collection.

Larry Pimentel said Azamara would benefit from its larger sister company as visiting private islands becomes increasingly popular among cruise passengers.

He said: “The islands have largely been developed by Royal Caribbean International.

“What we have observed is, when we have gone to these islands it is a unique day and our guests love it.

“I think you will see a trend to more privatisation within certain countries and regions – and we will be able to take advantage of that.

“A brand of our size would not be the builder but Royal Caribbean is bigger, so we can benefit from them.”

Pimentel added that guest scores strongly suggested that private islands owned by cruise lines were popular, adding they created “the perfect beach day”.
