You’re talking about the Carribean. It’ll work for the airlines. No St Thomas, that’s the US. Capacity may be an issue in those ports for awhile, but capacity can be built. Supply chain may be an issue, but that can be dealt with. Supplies can be loaded en route as capacity builds up. And, particularly with airline cooperation, Asian and European destinations can be ramped up. Not suggesting they’re not important already. The good thing for the US, at least Biden’s US, once these facilities are established, they won’t be abandoning them to return to Miami. To me Carribean cruises are just relaxing in the sun. I’d be happy to leave from various islands. I’ve spent a day or two early in Florida already.
Cozumel just built an expanded cruise port and offered it as a home port. Veracruz is a really pretty city.
