We enjoyed the cabarette shows (both the family@7:45 and adult later in the evening). We also always took in the shows at the WDT. I liked Fidelio in dueling piano but alas, dueling pianos is gone. There were some fun "adult" game shows in the evenings.
Later in the evening (towards midnight) DW and myself usually walk around deck 4, working off dinner, winding down for the evening, enjoying each others company.
