I couldn't find it on the Disney app, so I called the hotel directly. They renamed the show, and refocused it mainly on hula, but don't put the days on the app. It happens more than 2x a week now, but the guest relations person couldn't tell me which days. Just that it was right next to the pool.
I tried it and found it fun. You will see parents doing the game with kids, and maybe some adults doing it by themselves too. But it's not difficult, like an escape room level game.
If you have seen the weather report and it shows it is raining there, it might only be for a short time. Or in the mountains. Really anytime is a good time to go weather wise.
