I've got a mid-May 7:00am KLM flight HEL-AMS-MSP. I'm looking at the GoSleep Lounge (sleep pods) as a possible way to not have to get up so early.

It is described as "...in Terminal 2, inside the departure area, after Passport and Security control, in the Schengen zone, next to Gate 31"

I admit to not quite understanding Schengen, and I've only been through HEL once many years ago.

With my ticket&USpassport, is there any issue for me getting to Terminal 2 Gate 31 the prior evening? And then to my KL HEL-AMS flight in the morning?

And any other info anybody would care to share about this next adventure??

Thank you.
