erdaram, can we assume that if we had these passes and group availability was open early sunday morning that they'd let these in anytime the volume of people was low enough. we should be there at 8am on sunday
Please forgive the delayed response as my family spends most of every Sunday involved in Church activities.
I have never been asked that particular question before and do not know the answer to the last part of your question regarding getting into the memorial earlier than the time on your passes should there not be a wait.
The memorial is open 7 days a week from 10am to 8pm with the last entry at 7pm.
The Business office can be reached M-F 9am to 5pm EST at(NNN) NNN-NNNN I am sure that they will be able to tell you the rules regarding early entry if your are able to call tomorrow. If you are not able to call during those hours, please let me know and I will be happy to make that call for you and post their response back here.
My thoughts are however, that since they do not open until 10am and your ETA is 8am that you should get reservations for 10am and then that will still get you into the memorial at the earliest possible time.
Please let me know if I may be of any additional assistance and I would be more than happy to help!
