Was it worth it? Yes and no. It was great to be on a new ride, something we had never done before....and it was a really cute way to represent Frozen which I have no shame in admitting is one of my favs. Did it leave me wanting to do it again? Not in the slightest. I'm glad I got it out of my system and I'm pretty sure I won't ride it again unless it was literally a walk on. Not because it was horrible, it just isn't really that exciting. Once you've done it once, you don't really need to do it again.
We (myself, age 29, and a friend, age over-50) RD-ed it on my last trip and loved it, but for the next trip I'm going to try to get a FP+ for it for two reasons: 1-even though I loved it, it's absolutely not worth it to me to wait more than 15-20 minutes, and 2-this way I can avoid the 15-minute power walk back to Norway at RD.
This is what I'm thinking too - even though I may prefer Soarin or TT over FEA, I'm recovering from Achilles surgery, and there is no way on earth I can move fast enough to get to FEA at RD.
