We are planning to take Weidong ferry from Icheon to Qingdao.

We are a family of 3 member. Couple with one grown up daughter of 16 years. We want to take one Royal Class Cabin of Single Queen bed for three of us.
We are ok to pay the charge for 3 people, although we take one room. Is this possible ?

Also, is smoking permitted on Weidong ferry on any part, like open deck or restaurant or anywhere?

Thank you so much for providing these informations.
