From a tourist point of view it is just much easier to visit neighbouring Caribbean islands...
For foreigners, I understand it's probably easier to enter any of the other sovereign islands than a US territory, or (if you're from the EU), any of the colonial islands would also be easy.
If you need a passport, you need a passport. If you need a Visa, you need a Visa.
It might be cheaper or a shorter trip. But besides that it's the same.

Unless you take a cruise I guess.
And those are supposed to be features?
- Culebra has amazing beaches - Visit the bioluminescent bay - Visit El Yunque. You can do the regular tour or visit other trails. - You can go rapeling - You can go SCUBA diving - You can go visit reefs - You can go zip-lining
They're not limited to PR, but you can do them someplace new/different.
You can escape the cold. (45° here and raining. I _kind_ of wish I was back in PR)
