makes perfect sense. There is no iron-clad rule the show has to be pulling people from a packed studio audience. We know they've had auditions for the specialty events, and I know people who have been through the "Let's make a deal" interview process.
If anything, they could do a VERY classic tribute to TPIR because other than hearing the audience in the Bill Cullen days, you never saw them and really couldn't make out a bid coming from a single person. Four podiums on stage at a time, a game board wheeled out, even a "hands on" game like Plinko could be played while social distancing.
