Yes knowing what side of the road to drive on and understanding driving laws and being able to spend the currency you already have are indeed features.

Man, where is your sense of adventure.

[nkrisc]

People who want an "easy" vacation (per the original commenter) are not looking for an adventure.

Maybe not an adventure, but you can do some fun things.

- 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)
