Wow, now I am so glad I went last month when it was open. That was my first trip to DL so it was the ride I was most excited about too. I'm so sorry for those of you are going to miss it on your trips this summer! I would have been crushed if that had happened to us. That really stinks.
It did break down at least once when I was there, and one of the times we rode it the audio was off, and the we had to wait a few minutes at the boulder scene, which pretty much took the edge off the ride. But we went back on it again afterwards and it was fine.
It was our favorite ride--so hopefully the rehab will make it even better.
And as a recent first-timer to DL, there's a lot of other stuff to do. Can't totally make up for Indy being closed, but the new Space Mountain is fantastic...I actually did that more times than Indy!
