It looks like you're staying off property so, as Robvia suggested, a dinner show could work. We've seen the Pirates' Adventure Dinner Show and Sleuth's Murder Mystery Show, and I recommend both.
As for Citywalk, it has good shopping, dining and entertainment choices. For dining, there's Margaritaville, Hard Rock Cafe, NBA Restaurant, Bubba Gump's and Pastamore' just to name a few. For elegant dining, there's Emeril's Restaurant at Citywalk and Emeril's Tchoup Chop at the Royal Pacific Resort. For entertainment, there's a movie theater and Hard Rock Live.
