I too have taken 40+ pictures from the ship to the tram.

Disney has a from that allows kids to get off the ship. I actually have it in a folder on my computer.
This is basically what is says.
UNACCOMPANIED ASHORE Caribbean Ports of Call
I represent that I am the parent or guardian of the child/children listed below who are under the age of 18 and hereby authorize the listed children to debark the ship unaccompanied by a parent or guardian in the port(s) I have initialed below. I accept full responsibility for the actions of the children while ashore and release and hold Disney Cruise Line harmless from any and all responsibility or liability arising from the listed children being ashore unaccompanied by a parent or guardian as well as the acts of the children while ashore.
I know many teen parents like to use it. It also has a section to allow them to get off the ship with other adults who you select too.
I love the Christmas decor on the island. That is just so cute.
