Royal Caribbean International has unveiled new features on Explorer of the Seas after its $110 million overhaul next year.

The ship will be the fourth in the line’s Voyager-class to be transformed as part of the line’s $1 billion ‘Royal Amplification’ modernisation programme when it goes into dry dock in France at the end of March.

New onboard features include water slides called The Perfect Storm, The Lime & Coconut poolside cocktail bar, family-style restaurant Giovanni’s Italian Kitchen (pictured) and pool deck eaterie Johnny Rockets Express, offering American diner classics.

Activities and entertainment will also be overhauled. The ship will offer glow-in-the-dark laser tag, a new kids programme – called Adventure Ocean – for passengers aged six to 12-years old and specially designed spaces for three to five-year-olds.

Starting on May 7, 2020, Explorer of the Seas will sail seven and nine-night itineraries from Rome (Civitavecchia) and five or nine-night Eastern and Southern Caribbean sailings from Miami in winter.

Prices for the seven-night Greek Isles itinerary, departing from Rome on August 16, 2020, calling at Santorini, Mykonos, Athens, all Greece, and Naples, Italy, lead-in from £1,229.

During the summer season, an overhauled Allure of the Seas, which will go into dry dock early next year, will operate in the Western Mediterranean.

The itineraries include calls at Royal Caribbean’s new private island destination – Perfect Day at CocoCay.
