I booked a cruise on symphony of the seas for april 25 20. I called my the travel agency I used to see how much it was gonna be. They told me it was gonna be extra $2000 because the cruise price had went up. I have cruised solo before and know that I am paying for two people when I go solo. But I was always under the impression that all I have to do was pay taxes and port fees for the second person. Is that not correct or should I call royal to add person on later after the cruise is paid for being I went through travel agency or is that something that royal can take care of right now. Thanks for your help.
