I was at BB on Sunday and they closed all attractions around 5:30 due to impending inclement weather...it didn't start raining until about 15-20 minutes later which gave us time to find shelter. We left around 6:15 and it had died down to a drizzle and they hadn't reopened anything yet, but they were scheduled to close at 7:30. I'll be at TL this upcoming Sunday, so I'll let you know how that goes.
**edited to say that we always get there early...the only time since May that we've had to wait in line was this past Sunday...not sure if they opened the gates late or if there were just alot of early guests that day, but I would recommend arriving no later than 10 or 11 otherwise it's difficult to find a place to settle.**
