I am a foster parent, and would like to bring my foster son as well as my other children on our next cruise. Unfortunately, whether I will still have my foster son living with us when we travel is something I can't foresee right now. I am also trying to negotiate with the department of children and family services on being allowed to take him out of the country for a vacation. All of this makes for some uncertainty whether he will be travelling with us. So here is my question. If I include him in our reservation and if he won't be living with us anymore and therefore can't travel with us, how hard is it to make a change to the reservation to remove his name and get a refund? Would the better choice be to not include him in the reservation and add him later, or is that the more difficult option? Anybody have any experience with this?
