The best theory I have been reading was to totally avoid GotG for the first hour or so of non-EMH mornings, until the FP line goes down.
I've been told to:
1. Head to TSMM, grab a FP
2. Ride TSMM Standby
3. Ride CS (add other area attractions as needed until TSMM FP time is available)
4. Use FP for TSMM
5. Head to GotG, grab a FP
The theory is that FPs for RSR will be available later in the day so avoid it altogether until 2 hours after you grab your GotG FP.
I haven't tried this yet. We will put it to the test on Tuesday morning.
I should add that we have one of our group that won't ride GotG (or CS). We will be leveraging rider swap as needed.
