We have a cruise at the end of Feb and one of my three kids do not have a passport (he's only 1). I specifically asked our TA about whether we needed on and was give this guidance: Although highly recommended by Disney Cruise Line, at this time passports are not required for US Citizens on a closed loop sailing (Departs and returns to the same port). You will need an official birth certificate (with raised seal). After reading this, I felt comfortable having my toddler only have his birth certificate.....but then I started thinking about "what if." What if I had to (for whatever reason) fly from Bahamas back to US in an emergency? Wouldnt' that prevent him from leaving the country? What would *you* do? Help me decide what to do....we're short on time....if I apply today it will be exactly at the 6 wk mark (current processing times are 4-6 wks). Thanks to anyone who has input.
