747 Snooze Zone

Hello.

Could someone share some info on how beneficial using the upstairs cabin/snooze zone is on a 747.

My main concern is the speed of disembarkation. Am aware the top deck is shared by EC PAX but wanted to know whether UC are permitted to leave the aircraft first?

The Upper deck all disembark at the same time, and as the Y pax are closer to the stairs they will be in front of the UC pax. The upper deck is let off at the same time as the downstairs UC cabin, with PE and Y held back.

Thank you Neil.
