If speaking ONLY french and okayish English enought to get by over there ? do i need a eSim to translate ? or learn spanish at all?

​

how much is the food cost on average?

how much is the transport from BZE airport to the island and back ?

How much does it cost for taxi around the island ?

How does tax work overthere? like if I see 100$ will it cost 150$ because of 50% tax?

Whats the currency there? do they take credit card? is it preferred to pay in CAD or USD or their local currency?

my flight both ways are 660$ CAD

the hostel is around 50$ /days for 7 days = 350$ CAD

so I am around 1000$ CAD without insurance, food, transportation, but my budget is 1500$ so I feel im okay and can even maybe do 1-2 excursions

is my plan or calculation good?

any tips or place to visit or stuff i should know or cultural stuff?

​

EDIT: anyone has hostels recommendation for around 50$ CAD per day?
