I need a refresher tho. How is the tourism on TR completion calculated? It’s a % of the culture that has been generated in you empire since the TR started, right? So increasing TR speed will make these yields smaller, but more frequent, and overall the same?
No clue, to the modders with you!
If you want Hoover to just be the "take if going CV" wonder than I agree with your logic, but just to be clear....that's what it is right now. So then I guess the question is, is the straight CV boost better than the more subtle Smithsonian "more culture = faster policies and techs = even more culture = more tourism through historical bonuses and the like". My gut says that yes...the Hoover should be the stronger straight CV play. While its not the most exciting niche, I guess it is a niche...and technically the "standard" niche for America compared to vanilla VP.
So if we are going with this kind of Hoover push, here is my recommendation.

If we are going CV, than by gum lets push it. Making it hotels gives the wonder an earlier boost, and encourages a tall civ to get hotels in all of its cities (as Tall civs tend to be hammer starved sometimes they will just focus the hotel in the capital and ignore the other cities... this gives them encouragement). Also, Tall civs can often be coal starved (I have had many a game where I had zero coal as Tall)....so the factories could be VERY late in the wrong circumstances, whereas hotels are more consistent.
The extra TR just rounds out the economics, and gives them a little more bit of a general bonus that is not wholly tied to CV...in case they have to pivot late game.
