So 7 month DVC window for marathon weekend is June. Looks like I will gamble and book the (Aulani) DVC points I've been offered and wait a month for registration.
Since I am going to be training for Boston, I will look upon this as an opportunity to just come run in some warmer weather (which makes for a pricey training run, and no, I do not plan to tell my DH until after I've booked)
