Yes ! This is a very good example of how your Genie can help. Even if your non-SC friends have no dining package at all, the Genie can (and will) include them in any dining reservations that you want. They will need to understand that they will pay full price for their meals, but it will not preclude them from dining with you or from having the Genie make their reservations along with yours.
A number of years ago, we were traveling with a large group. We all wanted to eat at Wonderland (something I will never do again, BTW). 4 of us were SC but all of the others were GenPop and had no dining packages. The non-SC just paid for their meals at the end but the Genie made the reservations for the entire group.
Sorry, but I do not know Carlos. Sadly, many of the former Genies we have used over the years are no longer with Royal...there are so many new Genies. I know very few of them anymore.
