Harmony Of The Seas is due to enter service by the middle of next year, although if you are in the UK, there is a chance for you to take advantage of two sample cruises from Southampton before she heads off to Barcelona in June 2016, which will be her homeport.
The two cruises leave from Southampton on May 22nd and May 26th, where she will sail to Rotterdam in the Netherlands and Cherbourg in France respectively.
When searching on the Royal Caribbean website to book these two sample cruises they cannot be found, yet the Express has reported they do exist, and so we cannot offer any details on price. Having said that, we are sure there will be plenty of journalists on these two cruises, and so we can expect those early Harmony Of The Seas reviews to start coming in.
Update: Upon further investigation, we can tell you that the price of the Rotterdam cruise is from $469 per person, and $399pp for the Cherbourg cruise.
