If you do want to camp out here is the setup:
DCA will open at 2:00 am 7/17 for the purpose of holding guests waiting to get into Disneyland. - valid 7/17 DL admission will be required to enter DCA and ticket booths will be open. When guests queue up they will get their commemorative ears and whatever other gifts will be given out on the 17th. The commemorative ears are not the regular ones currently sold in the park, and they can not be embroidered. Limited refreshments will be available for sale inside DCA - Smoozies, Award Wieners (limited menu), ODV. Restrooms will be open. NO entertainment. It's a line, not a party. When guests enter the park they will receive a wristband. If they leave for whatever reason, they will lose that wristband. If they return, they will have to rejoin the line wherever it currently is at that time.
The Timon lot will be open, with tram service, for those who wish to camp out in DCA the morning of 7/17. The Mickey & Friends parking lot will open at 6:00 a.m.
DCA will stop admitting people around 6 a.m. Guests who arrive after that will queue outside of the security checkpoints at either end of the Esplanade.
Disneyland will open at 7:00 a.m. for an "unpublished opening." The DCA crowd will be escorted into Disneyland at that time. The security checkpints will re-open once the DCA crowd is inside Disneyland, bag check's will resume and people will be allowed to go right into Disneyland. It is estimated that it may take as long as an hour to get all of the DCA crowd into Disneyland, so the 8:00 announced opening time might be accurate for those who do not camp inside DCA.
They probably will not do the softer, staggered closes we're familiar with as attendance increases. There is a maximum capacity number, which has not been disclosed, and the park will close when that number is reached. When the gates close, it will be a hard close - NOBODY gets, regardless of their story
