Also, consider booking the FastPasses for the last day(s) of your trip first (or at least be flexible with your days and don't be discouraged if you can't find your preferred fast passes for the first or second day of your trip). The 60-day window (for on site guests) is only 60 days from the FIRST day of your visit. If you are staying for 7 days, you actually can book your FastPasses for your last day 67 days before you are actually there (because the window to book for your entire trip opens 60 days before your first day). As most people will book their first days first, and as the window to book for the last days of your trip will be open to substantially fewer people than people booking the first day, you can frequently get a MUCH better selection for the last day(s) of your trip (case in point, I booked at the start of my 60-day window and the earliest I could find a FOP FP on my second day scheduled was late afternoon, but when I looked at my seventh day scheduled, I could find a FOP FP almost anytime during the days from park open to close).
