I actually booked a FP for TSMM yesterday, for today. What's missing from "available" is that for my party of 2, I was given the option of 2 times. 12:25-1:25, or 5:50-6:50. I took the earlier, because we wouldn't be in the park that late. If you had a dining reservation that conflicted, it would be straight back into "you get the time we give you" territory of legacy. If you had a larger party, I wonder how "available" it was. And our "Yay, I don't have to run back and forth through the park 'benefit'" to get times in the mid-afternoon, ended up meaning we went Star Tours, ToT, TSMM...so we were going back and forth through the park. Thankfully, Studios is small. To really get the times to work out, the closer you can book to 60 days, the better. Yes, TSMM times can be available later, but you end up planning your entire day around that window.
