Yes, you should speak up...tell the bar staff, On my last cruise, sitting in the Solarium, reading, probably napping when a disruption was taking place on the first level. These were "adults" behaving badly, sound travels up, nobody needs to laugh that loud!!! After I spoke to the bar staff...(I asked the staff if this was a Carnival ship) LOL, he called security and the noisy adults stopped immediately and left shortly after.
