I haven't ever stayed down on deck 2, but I checked out the noisy room list on Dave's DCL tribute site and neither of those rooms are listed. I think you'll be fine.
I just came back today from the July 2-9 cruise!!! it was a blast! we got on deck 5, but I went down to deck 2, and it was very noisy. The floor shook & vibrated, and the engine of the ship was noisy inside and out. Not sure if you want to be on deck 2..
