I can attest to the fact that I was not always able to book the FP I wanted 60 days in advance, for the day and time I wanted. And, this was just for my wife and I, the year we got an annual pass. That lesson was learned for our first trip. With that experience, plus having read many reports and strategies, and armed with the knowledge of what rides were on our must do list, for subsequent trips I tried to create a plan that had the most difficult-to-get FPs not on Day 1. That was not always easy to do based on crowd calendars. I also learned the best days to arrive and depart (we always stayed on site) to help with the planning. I still did not always get the time I had hoped to get from my daily plans, but usually it was close enough that there was not much juggling of the plan needed. Essentially, I learned how best to use the system. But, it took a LOT of planning.
