I was at WDW Monday-Thursday. On Monday I went to the DHS around 1 or so and it was open but I didn't get to play the bonus round one of the times I rode. On Tuesday I checked back off and on all day and never saw it open, same on Wednesday. Yesterday morning I went back to ride TOT before I had to leave. I figured I would check TSM since I was already there, low and behold it was open. It seems very hit or miss right now. I know every time I rode I saw maintenance CM standing on the unload platform. That said, I would think it would be open this weekend b/c of the crowds.
