We did the “Royal Society of Puzzles” on Anthem last month. Not particularly well themed (it was basically just in a room) but fun. No charge for it at least.
To get to the page I was on, from inside an opened cruise, tap the calendar icon at the top center and then "Change Ship/Dates." That's what I usually do.
They’re actually different for each ship - which makes the ice skates for Odyssey even weirder.

This is the #1 thing I wish they’d fix in the app. It causes a lot of confusion. On the FB roll call for our December 3rd cruise, people were posting menus from the then-current Thanksgiving week cruise, sure we were going to be getting a holiday meal on Thursday.
