Question regarding PS4 Early Access

[Griever_Zero]

Simple Question,

How long will I be able to play be using PS4 early Access, going traveling tomorrow and don't know if I should take my PS3 or PS4 with me.

I get the Early Access code tomorrow, but I will get the game code with my physical vers. at a later date, earliest the 22th.
Will my Early Access be able to keep me in the game to that date or will I need to use my PS3 until otherwise?

To formulate the question in another way.
How long can I keep using early access without the "correct" license key.

P.S I'm aware that I could just upgrade my PS3 vers. But I would rather support SE for how they saved this game from Vers.1 and keep the option to play the PS3 vers. as well with the PS4 vers.
So no need suggest that possibility ^^

Early access is from April 11-14.

I'm well aware the Early Access is from 11-14.
But the question is, does the Early Access work after the 14th?

I could on my PS3 for some days after the Early Access date "ended", which was awesome, else I had to wait like extra 4-5 days since I first received the Physical copy some days after release.

Usually lasts for about two weeks after release.. To give ppl that ordered online a chance to receive their copy over the mail.

The original release only gave 4-5 days grace to receive the hard copy and use the registration code.
