The average ping from US, Florida to costa rica is about 180-210 ping. Ran some ping test.
Ran the test from my phone on 4g so idk where it was connected so the actual ping might be alot lower 
thanks!
Already saw on nomadlist.com etc. that internet quality seems to suck there as well - 200 ping range would be pretty much like what I have here in Paraguay. Well, anyways, it is not REALLY the main concern

- and the US and some other places (Belize, Dominica, ...) are not off my list yet. A lot of stuff is happening (good stuff, most of it), and we will see where the hermit washes up... ;-)
