Just got back from our trip on Friday, and this does not surprise me at all. We spent Wednesday and Thursday in the MK. BTMRR was up and running on Wednesday at rope drop. However, Splash was down for the first 90 minutes of the day. On Wednesday, BTMRR, Splash, and Space were all down at one point that day. The following day, both BTMRR and SPlash were down at opening. BTMRR was issuing FP, but Splash was not. I had to leave by lunchtime to meet my DH at TL. The boys and I finished everything we wanted to finish by about 10, so we stood and waited by Splash until we had to leave. My DS5 had never ridden it, and this was the one thing he wanted to do. When we left to use our BTMRR FP at 11, the CM I had been talking with gave me a Splash rider swap to allow the boys and I to use at any point that day. It had opened by the time we got off of BTMRR, and we ended up getting to ride before we left.
BTW, my DS5 loved it!
