About prices is myth.
You can get Capuccino in Monte Carlo for 2-3 EUR
Yes in Hotel de Paris and some luxury establishments can cost 15 EUR.
But the same in luxury Caribbean. Just look at prices in St Barth etc
You have Starbucks in Monaco even Mc Donalds.
About climate yes. Caribbean is full s**t and poverty besides St Barth. The only island in Caribbean which can be compared to Monaco
Where did you go for that ? Every place i went to was overpriced like hell, lowest i found was 7-8 euros and it was a well hidden spot lol...
Clearly need to explore further next time lmao
