Cruised on NCL Jewel out of NYC to N.E. and Canada and was somewhat mid-ship. The only time it was loud was when someone scraped the chairs across the floor on Deck 12. At night, there was hardly anyone on Deck 12 hanging out and during the day you aren't even in the room. I don't remember being woken up in the early a.m. if anyone was eating breakfast near the pool. If you want to be on Deck 11, try to get a cabin toward the front of the boat - the further forward you go, cabins start ending up below less busy parts of Deck 12.
