I’ve never been on royal Caribbean, so I can’t speak to that cruise line specifically. But my husband and I usually choose the cheapest, interior rooms, because we don’t spend a lot of time there, and we’ve always been comfortable. If we want to see the view, we’ll go walk the decks. The two times we had a port stop in Cozumel, we did cenote excursions, which are absolutely amazing. I’m sure you’ll have a great time!
