For the record, you CAN make a prediction on a ride before it opens and during the building process. People were doing that with the Fantasyland expansion, especially with SDMT. As a matter of fact, I see it happen quite often with the ongoing discussions of rumored attractions coming to WDW. I stopped keeping track of the progress on the Frozen ride (tired of seeing the constant debates on the ride itself). Now knowing it's going to be open before my trip, this is something that I have to take into consideration.
Why?
This attraction is one of many new additions coming to WDW in 2016. Obviously, this means that there will be a crowd increase. For me this is one more detail to take into consideration from a planning perspective. Personally, I have my own predictions about the Frozen ride and the potential crowd levels. However, I wanted to hear other thoughts for some comparison. With that being said, I'm not looking for sarcastic comments on a question that will most likely begin to start popping up more and more as the months pass. There are simply people who like to start their planning early and gather as many details as soon as possible.
