As a RCL cruiser, I actually preferred Labadee to Coco Cay, been to both multiple times. Ladadee you can hike paths and its a bigger area.
But I would not say no to going to Coco Cay. Probably will be a popular itinerary.
I dont see there is a chance that the two largest cruiselines would ever be allowed to merge. It would be stopped because of the lack of competition. (imo)
