As of this morning, if you call the first morning 90 days out from your first reservation (and, by the way, it seems to be the first reservation, they need to get you into the system 90 days out - they wouldn't let me start with my popular choice mid trip - PSB - I needed to make my first day reservation first), they will let you make reservations for the next ten days - pushing the window to 100 days, and keeping you from calling every day (and keeping them from having to staff the phones for that volume).
