It really depends if you can find a (cryptocurrency) exchange that lets you withdraw to a bank account in Costa Rica. If you can find one, you don't even need stablecoins. The way it will work is

US Bank -> Deposit USD to US cryptocurrency exchange -> Trade USD for Bitcoin (or some other crypto that has cheap transfers, it doesn't really matter) -> Send Bitcoin from US cryptocurrency exchange to Costa Rica cryptocurrency exchange -> Trade Bitcoin for USD (or local currency) on Costa Rica cryptocurrency exchange -> Withdraw to Costa Rica local bank

Theoretically, all of these steps can be done with less than ~$1 in fees. My banks and exchanges let me deposit for free and withdraw any arbitrary amount for 50 cents. Sending any arbitrary amount of cryptocurrency should be cheaper than that. The big question is if an exchange exists that lets you withdraw to Costa Rica banks, and what they charge for that.
