As a Uruguayan Tourist, I would surely consider that my spending be taking into consideration concerning many matter. This would be as I am aware of the prices in Uruguay compared to that of the Caribbean and I would not like to be found in the middle of some financial trouble while vacationing there.
This is why my spending limit would be surely maintained when in this country, or in any other country in the world for that matter, in which the currency is considered as better than in my own local land.
