>>2796574 (OP)>Greece, Japan, Argentina, Peru, and Brazil. Any place I should prioritize? These are all very different destinations, depends on what you are looking for.
>GreeceLots of museums, history, great cuisine in Athens, or Greek islands like Santorini for some Mediterranean beach relaxation and larping as a rich eurofag. Very romantic and ideal for a couple.
>JapanWeeaboo experience in Akihabara, cute anime cafes, karaoke bars, unique culture and great cuisine, but very touristy and crowded, you need to go off the beaten path to experience the real Japan. Less romantic than Greece, feels like it's better for solo travelling and even then only if you know Japanese.
>ArgentinaBuenos Aires is good for couples, it's bohemian like a pre-war Paris, with great cuisine (expect to eat lots of beef and wine) and an interesting art scene, otherwise you could head to Patagonia for a more outdoorsy nature experience hiking, climbing, etc. Or to the north to the Iguacu Falls which are shared with Brazil for some nature stuff.
>PeruYour girlfriend has to be into hiking 100% for this one. Anything worthwhile like the Macchu Picchu ruins or the national parks require hiking. There's some amazing beaches in the north coast (which are very overlooked but just as good as those in the Caribbean!), but it'd be a pity to go to Peru and skip the Inca trail stuff.
>BrazilBahia has great beaches (also Caribbean-tier), a very interesting culture and unique cuisine, I would avoid Rio. This is more of a relaxation type trip and requires less hiking than Peru, unless you want to go somewhere like Pantanal which is amazing for nature stuff, or Iguacu Falls.
>Can I do a week in Peru and a week in Brazil or are two weeks ideal for each place?I think it's best to concentrate on a single country.
