You will love Discovery Princess. Our DD liked Princess just as much as
DCL. It is different, but she liked getting to know the other kids better. Also, they will bring on the Iditarod dogs for them, do a lot of “myth busters”/“shark week” type stuff as they are tied in with Discovery channel. Also, they used to let the kids do a cooking class in the galley. Not sure if they are doing that currently b/c of COVID.
Make sure you try Alfredo’s. It’s an included pizza/Italian place off the piazza (there is another “regular” pizza place on the pool deck) that is really, really good. We usually eat there 3/4 times on a Princess cruise. And, it’s included. Also, on sea days, Princess does a British Pub lunch which is also included and very good. Lastly, make sure you make the “Yes/No” game show…
Have a great trip!
