No. I have asked this question of Princess in a few different ways and the answer I get is the 2 casual dinings per cruise do not refresh after each segment like the mini bar and other Elite perks. Now I think this is unfair. If I pay for a 7 day cruise or a 113 day cruise, on Plus, I still only get 2 Casual Dinings. Princess Premier is similarly affected with the Speciality Restaurant inclusion.
I think as loyal customers, we should be letting Princess know that this is just not equitable!!
