My regret I think is that in the several times I was at DL while the Rocket Rods were running I wound up not getting in line because it was always a 90-120+ minute wait and it really didn't look that great, especially knowing it was running on old tracks that were not meant to have fast cars running on it. That said, I really regret not riding it since now I will never know what it was like. Oh well, just to have it in my mental catalogue would be nice but it's history as is any chance I would have had to ride it!
I also really regret not going for an all night through all morning DL experience when DL had a special promotion in the early 90s where they stayed open for like three days straight. I wish we had gone and just rode Splash over and over as the sun rose. I've done a grad night but that only went until 4:00AM, all night and all day would have ben fun and I doubt they will ever do it again.
