I have told this story on the DIS before. When we were there in July two years ago, both TL and BB were closed by 10 am. We were trying to enter by car and we were turned away at the parking entrance. The guy at TL turned us away and sent us to BB. At BB they sent us back to TL. While all this was going on, what appeared to be locals were just parking cars on the side of the road and walking across the parking lot to enter. They were also still admitting buses and when we complained we were told that you would not be turned away if you came by resort bus. So unless you are going very early or later in the afternoon, you might want to make sure you use a resort bus.
