My favorite two lines are Celebrity and Royal Caribbean. Royal is best for fun activities like indoor skydiving, ice skating, rock climbing, etc. Celebrity has nicer ships and better food. The biggest thing I learned this year is that it's worth it to go on the better ships in the fleet. Royal Symphony and Celebrity Beyond were both amazing.
