I have conferenced at the S&D for several years. A vendor finally sprung to rent Jellyrolls out. Was my first time going and it was an absolute blast. It will be an adults-only must do from now on. Definitely a gem.
Since we are playing armchair BW Empire:
* More small venue clubs of different varieties: comedy, jazz, magic, a murder by the sea mystery dinner theater, etc. You could even have acts on rotation so a club was something different every night.
* High quality, late night QS-ish food options. (Disney is terrible at this one.) ESPN Club should be one of these places but isn't.
* Unique desert offerings that you can't get in the parks. What about a 21+ desert bar with all booze infused desert options.
* Some really solid "I partied a bit too much" take way options. Pizza by the slice is a good start but what about street tacos, hot subs, etc.
