I tried using that particular service in the past, but they could only validate US driver's licenses at the time and not passports.

Example of a good deal: Western Digital My Passport 2TB USB 3.0 Portable Hard DriveI would suggest thumb drives, but they fail more randomly and people lose/forget about them.

@Michael Kugler why not use Realist, Parcelquest, etc. to get copies of the property records, contact the owners, and if the owners are interested, have them send you identification, such as driver's license, passport or some other form of government ID?

-Puerto Rico tends to be very attractive for travelers due to several facts that distinguish us from similar vacation spots near by:1) It is a completely different country from the US with unique cultural differences ranging from food, music, language, history, customs, etc. but still having the many advantages of never actually leaving the US / so you get the best of both worlds (experiencing a foreign country without actually taking the risks of leaving a US territory).2)US currency is used, so no need to go thru the hassle of money exchange and conversion headaches.3) No visa or passport needed to travel4)You can find people that speak english in most areas of the island so no big issues with translation.5) You can also find some familiar and popular chain stores if any last minute items are needed.Now one of the most important facts to take into account is how the hotel industry works.
