Looking for an exotic vacation, but don't feel like flying halfway around the world? Many Yahoo! travelers think Puerto Rico
is a great choice for a short island trip. Only 100 miles long and about 40 miles wide you could drive the entire island in about a day — but why would you want to? With beautiful rainforests, centuries of history and great shopping, this little island is definitely not short on things to do.
Thanks to a quick check on Yahoo! Answers
I found out U.S. citizens don't need a passport to go to Puerto Rico. So if you're from the states, there's no excuse for not going.
