I have ran into a problem as of today. I took my kids to get passports today, and was advised that I need to have there father there to sign the passport papers. The problem is the father is absent in the lives of my kids and also he is not listed on the birth certificate. I was told that I needed to provide sole custody papers, and this is something that was never done. My kids are 10 and 13, are they able to sail with there birth certificate? I called and spoke with someone at Royal Carribean and was told that they could sail with a Birth Certificate, but she did not sound really confident. She kept putting me on hold, and then would come back and give me answers. Also my last name differs from my kids, and when reading about sailing with Birth Certificates it states the last name of the kids and parent must match. Please HELP...if anyone has ran into a problem such as this please let me know how it was handled. I have put a lot of money into this trip, and hate to get to cruise day and be turned away. We are traveling in July on Harmony, and will be going to Labadee, San Juan, and St Marteen.
