Eugene, I wonder if I threatened to use up my nine hours of satellite phone time listening to Naval Observatory time recording I might get priority back for excursions. :D
I'm not basing my supposition on anything except reasonableness.
It will be interesting to see what happens if we have 20+ G and H cabins for GRAND PRIX and we don't have the same priority for excursions as others. As for dining, all we have to do is book tables for six or eight with the ones actually doing the booking located in higher cabins.
I really don't see this as too big a deal.
