My FP window opened 11 days ago. My first weekend is a holiday weekend (Labor Day). I was able to get FoP for pretty much any day I wanted. Ended up with a set on day 2 (Sunday of the holiday weekend) and I think around day 7. Now, I was looking specifically for afternoon times, since we hop and like FPs to be at the second park of the day. Not sure if that helps with availability, but I had no trouble getting what I was aiming for. We are also a party of 2, so I'm sure only needing 2 at a time helped. If you can be flexible with Day and time, I would think you should be able to find something. If you are a larger party, it might make availability a little more challenging.
