But one CV from time to time could be fun.
Excellent!
So you are leading in science which means you will be fine for a CV.
I would just let my theatres fill themselves, throw an artists work into 3 museums and look for who might want to swap a bit of art with you. No big deal if you do not.
At this stage you could concentrate on getting Potalas Palace, intelligence agency and pushing spies if you like that way of playing... so even if full of GW, you can sell some to civs with lower domestic tourism to make room for stolen pieces.
I would certainly push for some seaside resorts and tree growing. Resorts really work well when surrounded by trees and this makes your civ look beautiful, it is the main reason I like resorts... resorts double tourism with Cristo of you can spam a lot more resorts with Eiffel, the later being the stronger. You have the science to do this.
Then if you have some faith a national park or 2 are also great and Eiffel helps a lot with these.
In essence I know you like pretty, you can have a really nice civ, more beautiful than normal pushing a mixed CV with resorts and parks thrown in because you plant so many trees and replace mines with trees too.
You should get a CV around T250 doing this and if it looks like it is not going to work, get some rock bands prepared and look for the tourism boost cards.
It is only fast CV’s that make your city look ugly.
I will often play for what I call a balanced victory... just play until 250 and think, how would I rate my civ? If you feel good you have won.
