We’re newbies to both WDW and TP. We had a list of things we wanted to see and do and I created optimised plans but then did lots of tweaking and rearranging to take into account lots of factors - ie not wanting to do Jedi Training at the hottest time of day, not wanting to leave must-dos until the end of the day in case we were flagging and wanting to go back to swim and relax, trying to arrange some of the air conditioned shows early afternoon, juggling around show times, eating at off times to avoid food queues etc And I did start to wonder whether all my changes have meant I’m not really benefiting from using the software!
But maybe the biggest benefit is just making a plan full stop? We didn’t really have any idea what we were doing when we went to DL Paris 5 years ago, and in hindsight we would have seen a lot more (and queued a lot less!) if we’d had a bit of an action plan.
