That happened to me last year, did Stay and Scream and went into Spirits of the Coven. Couldn't see diddly squat, and everyone that was around me was in the same boat. Granted, it made for an incredibly memorable run due to that, the kicker being the couple that was behind me. The wife was in a wheelchair, and she was the only one who wore sunglasses, so she could see. However, her husband who was pushing her?...could NOT see. So all throughout the house I'm hearing the gong show that was "Left! Right! OH GOD, LEFT! LEFT!!!!" Hands down the best run-through I had in that house.
While I don't recommend that if you're only going one night, but if you're going multiple nights, it might be worth giving a blind run a try!
It should also be noted that HoH literally bet their reputation that NOPE was coming to Orlando last year. It didn't, therefore, they have no reputation. Plain and simple.
