Later ADR at DHS after park closes?

[NMK62303]

Hi - I tried to search for this but couldn't find the info -- looking to book a supper meal on a Friday night in January (before the half marathon) at DHS but want to wait until DH gets in that night. I saw that Hollywood & Vine is open until 9pm but my question is -- do we just stay in the park if our ressie is for 8PM? Can we enter after it closes if we come from another park (we have done this before for breakfast ressies before parks open just not for ressies after parks close!)

Thanks!
