Dont know about the EOS but certainly on Adventure of the Seas I can confirm that you can clearly hear deck chairs being dragged on Deck 11 when your Cabin is on Deck 10. Fortunately it only happened around 7 to 8 AM when the crew was wiping down the deck chairs for the day ahead and we always happened to be up and about at that time. But if you sleep in beyond 7:30 then you COULD easily be woken up by the deck chairs being moved on the floor above.
Unfortunately we're back. The GS #1264 on EOS was wonderful. No noise from above and the room attendant was great. The concierge Ricardo was really very attentive and it was nice being able to go for hors d'oeuvres and drinks before dinner every evening. The only complaint I have is that the cruise was too short!
