Hesitate to differ with Robo, but many have reported veering right before castle toward the tea cups will get you to SDMT entrance a little faster, avoid the "crush" in the castle, and if running a little behind the front of the line, will also get you quicker to the end of the SDMT standby queue.
Are any others considering changing it up and doing Adventureland/Frontierland or Tommorrowland first and then hitting Fantasyland with FP+ for SDMT, A&E, PPF, EtwB, etc... in late morning/early afternoon (assuming these FP+ times can be obtained), to avoid the masses.
