During our ABD CA trip last oct, there were people on the tour who were developing the WDW trip, and joined with us on activities to see what is done and how it is done in CA. They asked us questions about our favorite parts, and they were taking lots of notes and it was really cool to have a heads-up that this was coming...but I am surprised it was this soon.
We are closer to WDW FL, but we are still interested in doing ABD FL in 2018 or 2019, after the new stuff is opened. I think behind the scenes access for the new stuff would be epic, and since we only go to WDW every 5 years on the platinum plan, this seems to be around the same value for us. For those who go every year, I would think, would not be ideal, but for special occasion WDW trips....perfect. (2018 would be our 15th anniversary, and we went to WDW on our honeymoon, 5th anniversary, and 10th, all on the platinum plan.)
