Despite people chastising you for asking this, I think it is a wonderful question and very valid. Sure there are many other problems in the world, however, when you pay good money for a Disney Vacation, you would like to think you can get a picture of the iconic castle and/or you in front of the castle without a huge crane. I have lamented about that as well. But I will tell you, even when there is not construction, it is often there for putting up lights at Christmas and other times. I looked it up and can find no actual dates listed for completion. on Disney's site, it just says things are opening through 2014 so I'm thinking if you want no crane, avoid this year and avoid November when lights are going up on the castle in preparation for the holidays.
I do think you can get some side angles of the castle with your family. There are a few photos at other locations besides directly in front (like one hangs out near Crystal Palace), but I think you would just have to luck out that the crane was moved at that point. I would say, you yourself could find a side angle and just ask a person walking by to take a picture for you. It can be very frustrating. I still look at our November picture and lament at the crane!! I feel your pain. Good luck.
My gosh, no kidding...what is the deal with people feeling this uncontrollable need to flame other ppl. who express something that is not ideal for them. I wasn't aware that this was the "3rd world problems" forum...oh wait that's right it's not, it's the disboards and specifically a forum board about the theme park.
OP, you asked and vented and very valid question/complaint. Hopefully it will be down for your trip, but regardless have a great trip!
