There’s a hybrid approach that works pretty well now in the remote era.

I’ve used a platform called Baselang, which basically gives you unlimited access on demand to get in zoom with people in Latin American countries to have conversations in Spanish. They do have a structured curriculum but actually having direct 1:1 conversations is not too far from actually being in country and practicing.

I have no connection to the service except as a customer and there may be others as well. It’s a model I recommend. I’m already fluent in Spanish but it gets pretty rusty and my vocabulary fades so I’ve been using it to stay current.
