I will be at WDW 9/18-9/22 with my DW and DD 9 will be staying at POP and have all my ADRs in place.
The guides show the crowds to be pretty low those days. Is it worth it (Pay TGM or TouringPlans) to put together a detailed plan for each park or it will the crowds be low enough that if we hit the big rides early we will be ok to just play it by ear. We are planning on visiting MK on Monday after check in early morning, Tuesday for early morning hours at Epcot, Wed at MGM, Thurs back to MK for early morning hours, and AK on Friday for the last day.
