Sent this to a few of my buddies for our upcoming trip.
Just what I am doing, not a recommendation, do your own research.
FYI: insurance
Thru Sagicor my insurance quote for 16 days is 162.00.
Thru Tarwick which is the U.S. "equivalent"; quote is 338.00 so I will go Sagicor.
Sagicor is CR based and if you go with them or the CR INS National program both only require 20k coverage, Tarwick 50k. Also i quoted both 2500 and 4500 for the cost of trip / lodging insurance, no change in rate, I will use the 4500.
The health pass also called [epidemiological] gets completed 48 hours before travel, and needs to have your insurance policy number attached.
I also saw posted here that addition to the QR code and info on your phone; you should also have printed copies for customs and immigration. Whatever makes it easier, right.
Start here it has links to everything in the page, and current updates on curfews etc.
