Summer 2024: Where in the world to go?

Turning 30 this year and itching for another big vacation but need recommendations on where to go next summer. Leaning Europe but also open to South America, Asia is a distant third (just went). The only place I'd rather not see again is Italy, spent a good bit of time there a few years ago. I would rather not stick in one city but be able to move around, would like to see the tourist sights but also looking for a good time.

Initial thoughts: Greek islands, Northern Europe (Netherlands/Denmark/Sweden), SW Europe (France/Spain), SA (Argentina/Chile)

Appreciate any and all ideas
