Corporate was designed for tax efficiency at every club.
As for "clueless tourists", football tourism is a huge industry. Wealthy people booking holidays around PL/CL fixture weeks is a massive money spinner. For example:
Saturday PL at the swamp, Sunday PL at Arsenal, Monday at Brighton, Tuesday Spurs CL, Wednesday Chelsea CL, Thursday or Friday travel home.
They'll do the same type of organised trip to Spain or Germany etc next year.
People will definitely have done this as part of a package holiday, and they'll have spent hundreds in club shops at every venue.
It's modern football, driven by media hype. Clubs are simply targeting the market via ticket agencies etc while it still exists.
