I'm of the mind that it's never really to early to start planning a Disney vacation, as long as you keep flexibility in mind. However, some of my friends and family think I'm nuts when I start talking about a group trip that we're planning for October 2018. Do your travel companions start to roll their eyes when you talk about things years in advance (like Star Wars or Toy Story land? How to you deal with that? Is it ever to early to begin thinking about a Disney trip?
