The four port fairly short cruise hits interesting spots in northern Spain and western France . . . especially interesting is the Normandy visit.
My wife and I have cruised over 70 times, mostly in Europe. Not a fan of Royal Caribbeans promenade design as it brings everyone to a central place and results in crowding. It is almost impossible to get a cup of coffee after a show in rhe one and only open location and there is no late night food available anywhere without paying an extra fee.
We also normally check the ratio of inside cabins as a high number tends to overload public ares . . . the Adventurer has far too many! he ship is mobbed.
