According to the AAA Memorial Day holiday travel forecast, 37 million people are expected to travel over the long weekend this year, up 60% from last year. That said, the Centers for Disease Control and Prevention (CDC) recommends not traveling unless you’re fully vaccinated — as in, it’s been at least two weeks since your last dose — following local guidelines about mask-wearing and social distancing and taking extra precautions if you haven’t been vaccinated yet.
