Using BTC in El Salvador (Reddit Bitcoin)

Hey BTC Community, I’m heading to Bitcoin Beach in El Salvador at the end of the month. I am a US citizen living in the state.. How can I use bitcoin to buy goods and services when I am there?? I was told to use the Blink Wallet, however, US citizens cannot use this.. the whole purpose for my trip is to see how bitcoin is traded in this country.

Any suggestions as to what wallet a US citizen can use? Thank you.
