They were giving out the double walled cups with the screw on lids on the Mariner Cruise I took this past May..we never used them, I could see why a younger person would think they are pretty cool.
1 experience EClass, Apex this past March, really enjoyed most things about the ship. No issues finding quiet when I wanted it.
OP seems fairly dramatic with the complaints to me. YMMV.
No wonder our insurance keeps going up. I choose to travel, hence I need a test, I will pay for it myself, and have. 3 times for the Wife and I so far.
$25 PP is cheap, if that breaks me, I need to rethink things.
I also found it very hot and not breezy at all..one and done for me. 12th deck SV on Apex. This was in the Caribbean. It might be better on a cooler weather cruise.
