No real pattern. For example, at Epcot, we like to spend the afternoons in WS. So we loaded up on early FPs at FW. Not because we expected to get more. But because we don't plan to be there after 12:30 or so. And for AK, it is sort of the same. We will arrive at RD and do what we normally do for the first hour or so, all Standby. Then, before we are ready to call it a day, we will make one last circuit of the park using our FPs from 2:30-5:00. At MK, one day we will use morning FPs and hope to get more in the afternoon. (Crowd level prediction is a 4 or 5). If that fails, then Oh Well. The second day at the MK will be one where we sleep in a bit. So we will arrive in time for lunch, and then use FPs in the early to mid-afternoon. I would probably re-think all of this if I thought that the crowd levels were going to be 7, 8, 9 or 10. Our plan pretty much depends on the crowds being less than people have been experiencing over the past month. If that turns out not to be the case, we might be in for a world of hurt. But again, if crowds are ridiculous in the third week of April when predictions are for 4s, 5s and 6s, this might be our last trip to WDW for a very long time.
