I am a portuguese speaker, and do not speak english (using Google translate to post here) and am flying to Miami. My layover at PTY will be last 15 hours, and because I do not speak english or spanish I am very anxious about it.

I want to know about the areas I should avoid ( so i am not leaving the boarding area) and what is there to do in the airport while I wait.
Is there free wifi?
Are there recharging areas?
Can anyone provide any info that might help me?
