Just an offer of an idea..
If Price were to go on the road, many of the games could be (only for road shows, mind you) done with projection screens. Backgrounds too. The only props absolutely needed would be the wheel, showcase podiums, contestants row, and games that couldnt be computerized. Just on the top of mind, lucky 7, 3 strikes, clock, and others would work.
Further, certain components of the set need not travel at all, like the turntable, and the show could be done with 2 doors instead of 3. To solve the contestant processing problem, only process the first 400 and seat them front and center.
And before anybody says something like "that just wouldnt feel like Price," sure it would. As much as a road show is GOING to feel, seeing as how they just havent been done for a lot of good reasons.
