Sounds you just had a run of bad luck that day.
We were there that same day from about 12:15 - Closing and thought we had a good time. What time was IJ down? We rode it at about 8:30PM.
As others have said, if you step back and look at your trip you really did get a lot done. Reading the boards here a lot I know that rides do go down, so if I miss something I miss something. Like yourself though, I'd be pretty bummed about RSR being down all day. We just love the atmosphere more than anything else so we'll definitely be back. I think one of my favorite memories is just sitting on a bench in front of Starbucks with my Iced Carmel Macchiato, enjoying the street entertainers, and watching all the families walking by.
