Hi all, I have been following this board pretty closely as we will be in Portugal from June 12th to July 3rd. I wanted to post something I just read about testing in case people were not aware since I wasn't.

You can use rapid tests if virtually administered to get back into the USA. You can also book these appointments for the tests in advance. This is also noted on the CDC site under the FAQ "Does a self-test meet the conditions of the Order".

This should at least make testing easier coming back to the States.
This one seems to have plenty appointments and you can buy the test on Amazon to get same day shipping.
