DH and I had a Signature Suite on the Oosterdam in 2020, 1 week before the shutdown. I thought since we were under the Canaletto, we'd be OK soundwise....but no. DH is a light sleeper, and all he could hear was the thump, thump, thump of the carts on the ceramic tiles on the Lido. There is a room right across from the Canaletto where they drop off food waste, bowls, etc., so there are carts going by all day, into the evening and then early in the morning again.
Didn't bother me, I can fall asleep anywhere and anytime....but DH said never again.
