Nope. They went into full shut down, people trying to return in the afternoon were not let back in until the wee hours of the morning. If you go and capacity crowds are a potential do NOT count on getting back in, there were lots of angry people on Twitter who made the mistake of buying tickets and leaving the park who were unable to return that afternoon. I believe reports indicated they allowed returns briefly as part of the shut-down stage but then they closed out everyone. Even people with dining reservations were not allowed in once capacity was reached, there was no work around. If you make it in, stay in!
Bet that was the only day people every read the terms and conditions on the back of their Disneyland ticket
It depends on what level/stage closure the parks have reached. DLR has not published how they define capacity closure stages, so it's all guessing at this point. Based on the 24-hour day, the first closure restricts new entries into the park, but re-entries are allowed. The final (most severe) closure stage prohibits anyone from enter the park (so it doesn't matter if you have an ADR or not). There might be some middle stages, but it's not clear what they are.
Unlike DW, I don't believe DLR makes public what their closure levels entail. I know that on the 24 hour day they closed to new admissions early in the afternoon, but were allowing re-entries until later in the afternoon when they completely closed DL to everyone. Once it was completely closed they did not allow anyone, so if you have a dining reservation, I would get there early and not leave the park. They didn't start allowing those who were already in DCA when the full closure went into effect to enter DL until 3 AM.
Disneyland was for sure opened July 17, 2005 because I was there!
