Mmmmmmmm, don't know if they will let you in, it will probably depend on the CM working the turnstile.
They usually let you in at 4pm with an MVMCP ticket, you'll need to go in about 3:30 though with a 3:50 reservation. It's only a half an hour, but ya never know.
Could you change the reservation to maybe 4:15pm just to be sure you don't lose your ADR?
That is what I figured Beatty... ah well. I guess we will enter at 4 and see what happens... if they seat us, great, if not, we will do counter food :::: Sigh::::: I will keep calling back to see if we can get a later ADR though...
