The Itinerary Planning Office will make any and all reservations for you. They schedule the Safaris, make dining reservation, answer any questions you have, etc.. . You can contact them right now if you wish. Sometimes they have make the first contact, other times I have.
If you have not heard from them by 100 days out or so, contact them. Since all reservations are at 90 days now, you will want them to get set to make yours. I usually make my own dining reservations but ask them to make Safari reservations (they're the only ones that can do that as best I know) and on occasion for a difficult to obtain reservation. It will probably be a while before we stay club level again but I'll probably ask them to make all my dining reservations in the future if the process has become as cumbersome as some reports indicate.
