I am really torn about this ride for our trip in February. Me, hubby, 20-year and 12-year old daughter going. We all love Soarin and Test Track, so I don't think I am going to use my one Tier 1 fast pass on this, even though we like Frozen as well. I will wait until another trip to ride it. After February, our next trip might just be a while, so the hype will hopefully have died down.
We are going during a slower time frame, but our Epcot day is on a Saturday, thus it will probably be busy. So getting to ride Soarin and Test Track at least once with very minimal wait will be my end goal I suppose. I have thought about the idea of getting in line about 10 minutes before closing too for Frozen.
