-Piety - grab a couple religious buildings in your religion (Cathedrals are best for this), then grab Sacred Sites as your Reformation belief. City spam to get lots of Tourism without any GWs.
-Aesthetics - lots of related Culture bonuses, and doubles your theming bonus as a finisher, as well as allowing you to purchase all GAs with Faith. A must. Also unlocks the Uffizi.
-Exploration - the opener and finisher are the best here - the Louvre is awesome, and being able to raid hidden sites no one else can see is awesome.
-Ideology - they all have Tourism bonuses, but Freedom is the best, with the 3rd level tenet that gives +34% Tourism in cities with a Broadcast Tower. Nab the CN tower and you're golden!
-Wonders: Obviously any of the ones with GW slots. Eiffel Tower directly gives 12 Tourism. Leaning Tower increases GP production in all cities, and gives you a free one.
-Guilds - Spread these out between three cities (preferably on a river or lake for a Garden) to even the Specialist load, and get them early. Don't save GAs unless you don't have a GW slot open - you want that Tourism pumping out as soon as possible. Until you're making at least triple digit Tourism, GMs should be turned into GWMs, and not sent on Concert Tours. An 11,000 Tourism bomb is much more useful than a 100 Tourism bomb.
-Science - Beeline for the wonders mentioned (on lower levels, GL->D&P->Parthenon is awesome). Once you're in the modern era, beeline for The Internet, which takes you through Hotels, Sydney Opera House, CN tower, and National Visitor's Center on the way. Once you have The Internet, double back for Radar and Airports.
-Archaeology - Whenever you have a city with decent Production with nothing that needs to be done *now*, pump out an Archaeologist. If the site is in your borders, make it a Landmark. Otherwise, take an Artifact. Go for ones outside your borders first, before other civs snatch them up, or they get sucked into their borders (massive diplo penalty for stealing artifacts). Be mindful of Museum theming bonuses when choosing!
-World Congress - If you can shove through a World Religion, do it. Otherwise, the proposals that gives extra culture to World Wonders and Specialist Improvements/Landmarks give lots of Culture fodder for your Hotels. Also, you obviously want Arts Funding. If World's Fair or International Games are up, make sure you get first place! +100% Culture is too powerful to allow an opponent to get, and +100% Tourism can make the game end much more quickly in your favor.
Remember to theme! Hover over to make sure you're getting the maximum bonus! Make sure your GWs are only in cities that have Hotels.
If you do all that as Brazil, you should win on Prince before the Modern era ends.
Best civs: Brazil, France, Polynesia
