okay so let me say it this way, RCI hopefully will RESCHEDULE tours to earlier time. Otherwise, a lot of passengers will have to walk around the port and try and book stuff on their own which IMHO is not such a good idea in case anything happens.
And perhaps RCI does create shore excursions in conjunction with the tour operators.
We do not know what really goes on behind the scenes, but I know a lot of the Juneau port excursions will need to be changed to earlier times. Almost half if not more won't go if they don't.
