This January my sister and I will be back at WDW for a few days. We've both been going to WDW for decades and are always looking for new stuff to do. We don't have a ton of money to spend but we briefly discussed doing a tour. I think we have it narrowed down to Keys to the Kingdom, UnDISCOVERed Future World, or Backstage Magic. Backstage Magic is a bit too expensive for us but not completely off the table. I've done Keys to the Kingdom before (although its been probably close to 15 years ago now) and she's never done any tour. I'm mainly curious about the Future World one though. I've looked around online a bit for info but there isn't much specific out there. What places are visited? Worth it or not?
