You have to have paid in full before shoreside can help with reservations. Since I had only paid for our suite before the 125 window, they could not book port adventures etc for the members of our party in other staterooms (non-concierge at the time, I later upgraded everyone). Shoreside was creative, however, and did everything they could to accommodate my requests, including adding Remy reservations for everyone. We got our cabana and van+driver with room for the full party as well so the only remaining problem ended up being the port adventures where you book for each person individually. When shoreside made me aware of the issue for the guests who were not PIF, I paid off the balance and they immediately made the last few bookings. They really did everything they could within their rules to help us.
