Oh Karen, I'm really sorry, I'm not on Facebook and didn't realize you were already organizing this. I only offered if no one was working on it. Like I said I have no experience with it, I probably wouldn't have even done the google doc, so it's good you're taking care of it.
If it helps, here's the text that the lady posted from my last cruise on how she ran it.
Stateroom Tour
Take a peek inside almost all categories of Disney Wonder staterooms courtesy of DISBoard hosts who will open up their home-away-from-home for you to see and compare to your own digs.
We will travel together as a group to each stateroom for viewing. Maps and directions will be provided at the meet location. Stateroom hosts will be at the front of the room view line in order of rooms to be seen. Thus, the 1st person to enter the 1st room to be seen will be the owner of the 2nd room to be seen and as soon as they are done seeing the 1st room, they will depart to open their room and wait for the rest of the group to arrive. They will follow the group to the 3rd room to be seen upon departure of the last person to view their room, etc.
