You're assuming that there was a constant wait. Not to lecture, but try not to think about fastpasses in terms of being the only way to successfully tour the parks. It's not an absolute - if there's no fastpass then I must stand in this particular line and wait for an hour. You do have the option to walk further down the path and circle back.
We were there during two weeks ago. About average in crowds I would say, and the longest we waited for an attraction was maybe fifteen minutes. If the attraction had a long line we simply went to another. We got to the parks early and hit the big ticket items first. Those others that typically had minimal or no wait most of the time were hit later in the day. Would a fastpass saved five or ten minutes in one of the 'longer' lines? Perhaps, but again I never bothered to check for one in the first place because there was no need and it's not my style. I didn't need to reserve a space in line two months ahead and plan down to the last detail in order to consider the trip a success, and if a fifteen minute wait is the penalty I have to pay then so be it. It's a small price to pay to avoid the negatives (subjective) associated with having to plan the day out way in advance. Granted, if this or any other trip resulted in continuously standing in lines half an hour or more regardless of the touring style then fastpass would have been a forced option, but there are ways to navigate and avoid locking yourself in.
