Hi Steph!
Just like you we are Carnival cruisers. We have done 2 MSC cruises, One YC one not.
Nothing like the YC! We did YC on Seaside (like you) and Divina we did Bella which convinced us that the YC is the way to go for us!
We will be going on the Seashore in October (Halloween cruise) in the YC and are so excited to get to Ocean Cay. We never made it the last time it was scheduled due to high winds.
We also have 3 Carnival cruises in our near future and as you said, Carnival is home.
Have a blast and I will be following!👀
