Stayed at the Sheraton at MXP last week. Through the glass doors in the lobby, had a Rapid Antigen Test for 40 Euros. Got the results in 10 mins. Then took the elevator to the hotel bar/resto and had an Aperol Spritz and went "Whew, that was easy". Crazy thing though, no one asked for or looked at our test results or that silly ATTESTATION form. Not when boarding in Milan, not when arriving and departing LHR or PHX.
PS/ATMs in Spain are not tourist friendly.....depending on the bank, the fee charged is waaaay higher than we're use to. We waited to get to France before getting Euros from an ATM and just used our no transaction fee credit card while in Spain (3 ports).
