Get outa here with that nonsense!

Passports. I thought that was it. It was all we needed for our honeymoon. A passport. The travel agent even said you'll have to get a passport. BUT when I went to get all the info we needed, it asked if we were applying for a passport card or a passport book. Hmm? A passport. Don't you just have an option for passport. Call me sheltered, but I am not familiar with the whole passport process. I know you have to apply and pay and get your picture made and show proof that you are who you say you are. BUT the card and the book just threw me for a loop! I'll have to investigate more, I suppose. Unless, you know the answer? :o)
