I had a colleague at work, who had been to WDW before and had shared stories, experiences etc. BUT, he knew best for his latest trip and would not be persuaded that using MDE to book fast passes before you arrived would be a good idea
" We'll see what we get on the day"
At that point I never bothered on sharing much more.
Head hitting brick wall and despite advising on looking on The Dibb to help, he knew best
At least he did it his way- not sure he will be going back though
