Unfortunately this was never gonna happen during a peak travel period like spring break, and when the laggard family finally wanted to book the price had gone up, yes, 4500 bucks. Goodbye, vacation.
Sally has another tip: families who find it hard to commit can buy "price protection insurance", so that if you do book far in advance and the price does drop, the insurance will refund the difference. (Cost is about $50 per person, it's up to the traveler to monitor prices, and there's some more fine print.)
