My friends and I are going to Puerto Rico for a week and are renting a condo. The listing seems legitimate. The listing is on Trip Advisor and VRBO.com with about 20 positive reviews. The contract states that I need to give all my credit card information to secure a deposit. (Paypal can be used for the actual amount). Is this normal?? Safe?? I'm pretty weary about doing this. Any help would be greatly appreciated. Thank you!
