This is a paste direct from disboards.com:
"Parks With FP Tiering
In Epcot and Hollywood Studios only, FP attractions are divided into two groups, also known as tiers. Guests are able to make up to one selection from Group 1, and up to two selections from Group 2.
Alternatively, guests can also make all three selections from Group 2 if desired.
A second Group 1 attraction in the same park can be scheduled only as a 4th FP or beyond. In other words, scheduling less than 3 FPs for a day in a tiered park is not a shortcut to getting a second Group 1 FP faster."
So, if this is true, I'd schedule the 2nd and 3rd fp as early as possible, I guess, and knock them out.
The conventional wisdom, I think is to RD Soarin, single ride Test Track, and FP FEA if you want it.
Recently, Thursdays have been EP's am EMH day. A few weeks ago on the AM EMH day, I was able to get in Soarin 2x and TT 2x using only one FP for TT. Would have all been pretty much walk on, but TT went down for about 15 minutes.
