This will be our 5th cruise and our GS is now 10 and GD 9. We have not up to this point allowed them sign-out priviliges. They know the layout of the ship and we have been in the same room location for all cruises. We go in August and they have not asked if this will be given to them this time. I know they are old enough, know the ship are good kids BUT I fell uncomfortable maybe because they are grandkids and not my own kids. If you give this to them in the beginning and feel that it is not working out can you change? One other thing, all day excursions are planned with the kids but they probably will not want to go to Key West or Cozumel with us at night. I also know that it is my desicion, only asking for advice.
