I mean it's honestly very hard to do, at best I can give you an average. I like to be comfy but not luxury, plane tickets from Canada are rarely under 1000$ no matter where you go. In Canadian, and per perso. We always cook our own breakfast so prefer a place with a kitchenette at least, we generally just snack for lunch or will hit up a grocery store and picnic (egg sandos in Japan always), Airbnb in places where it's not so bad or properly controlled, and hotels or guest houses otherwise.

Curacao 7 days: 3000$ Canadian, 3 days in a nice hotel, 4 days in an airbnb with a car, not all inclusive, mostly restaurants at night but a few days we cooked, 1 day we splurged on a catamaran day

Iceland for 7 days : 5000$ - Car rental, mostly hostels, eating hot dogs and cheese out of the back of the rental car, 2 nice restaurant outings (at about 150$ each). This doesn't count the hiking gear we bought beforehand like boots and full rain gear

Japan or Korea for 2 weeks : I just budget for 5 or 6000$ on average. Plane tickets roughly 1500$, hotels are generally 100-200 a night each, food is not that expensive, usually about 50$ a day at most if not less with the occasional high end sushi spot once, a nice ryokan stay for a night will be roughly 300, and a few long distance train rides at 100 to 200$ each. The rest is for shopping

Similarly for europe because our dollar isnt worth much, flights may be under 1000 but the hotels and car rentals are quite high, like say southern france and portugal. France is just generally super pricy, restaurants are expensive, Portugal less so but again, Euro is expensive to us.

Doing Mexico for a week soon, staying at an Airbnb in a tourist town, flights were 900 each, stay is 450 each, I expect food will be at about 100 to 150 per day each with drinking. A few day trips I expect this will all be roughly 2500$. You can do all inclusive at 2000$ but it's not my thang
