Why Are Mets Opening Day (Night) Details At Citi Field STILL A State Secret?

Just saw a commercial on SNY asking me to “show up early” at Citi on Monday.
 
First of all that’s really unfair to ask someone to show up earlier than 7pm..I mean it would be so hard for me to get out of bed and….oh wait I’m not on the Padres.
 
Anyway, HOW EARLY should I come?  Why is that a secret.
 
Maybe they have an amazing celebration planned.  Tom Seaver is going to jump out of a birthday cake.   Mike Piazza will re-enact the Michael Sergio parachute jump….
 
…whatever it is, I can understand if you want to surprise us….
 
…but why is the time a secret?
 
Couldn’t you tell us “6:10, and a surprise VIP will be there!”
 
Something.  Anything?
