No does not, but there is a "master" switch (On Allure) that controls everything, be carefull not turning this one off when you leave the cabin.
Ask your room attendent on the first day.
You basically board the ship based somewhat on the order you check-in, as well as your Crown and Anchor status and/or if you are staying in a suite or not.
All that being said, the earlier you check-in, the earlier you will board.
Yes, I have seen it offered at the R-Bar and Vintages. Obviously what is offered depends on your ship and sailing, but I saw it offered on Navigator of the Seas earlier this month.
Being in a group gets you more "power" with RC, meaning you can get rewards for having more cabins booked. This can be used in the form of onboard credit, money back to the group leader, special events, etc.
When dealing with groups in general, I always advocate using a travel agent to assist you in all the nuances of managing a group.
This, by far, was one of my favorite onboard, extra costs activities when I was onboard the Disney Fantasy. Unfortunately, I have not seen such a class offered on any other line, including Royal.
