I realize that my post may have sounded insensitive, and I apologize for that. After I went back and read it I could easily have sounded like I had a tone...
You personally, and your post individually, may not have delayed the refurb. And, you are obviously allowed to be bummed about the attraction not being open. I would be too. Most people don't take multiple trips to WDW per year, and many don't take annual trips. So, when something isn't operational during your trip, it can be years before you see it again. I remember being at EPCOT in October 1999, for the first time in several years, and not being able to ride Horizons. I was heading to college that following fall, so it was the last trip I would be able to take to WDW for a long time. As bummed as I was at the time, I was actually pumped to ride Horizons again after its "refurb" when I would eventually, someday return. Sadly, we all know how that one worked out...
More recently, I remember when Living with the Land was closed a few years back during my short vacation down to WDW. We were bummed. I actually called WDW to ask if the information I had was correct - and they confirmed it. They also told me that many, many people had called to complain and protest the short ride closure. Now, it is unlikely that a single complaint would delay a refurb. But, I worry that the attitude within the WDW management is that it is better to let an attraction rot than face the barrage of complaints that result from a period of closure, and that the attitude is a result of people complaining. Maybe I am wrong. But, it is something I think about.
