This is the case with carnival also. Very limited Brands available. Almost all of these are Bar Pour Brands that most people have never heard of. I think People that purchase Cheers would be upset about not being able to get the brands they want so Carnival states that Cheers does not start till day 2 of the cruise
Being this was an Hawaiian cruise, the differences could be because of the sales tax that is charged could be different for each island, while no sales tax is charged while "at sea"
As one of the handful of cruisers that take up all the good seats, you can always get to the piano Bar Earlier. We usually get to the venue 45-60 minutes before stated start time so we get the seats we want.
We have never sailed with Oliver. Will be on the Conquest with him on Aug 8th. How have, any of you that has sailed with him, enjoyed his show in the Piano Bar.
