Going next month...
Passport - new one received a couple of months ago, signed where requested
ESTA - approved (will print copy)
Monzo account - opened just waiting on card
Travel insurance - done (will print copy)
Booking from travel agency and payment confirmation - will print copy
Extra ID for when there - will take drivers license and old passport, which was returned to me
Cash - will take a little but mainly card
US plug adapter - will buy this weekend
I'm hearing something about API (Advanced Passenger Information)
What fresh hell is this?!
Any help would be very welcome. I'm getting nervous
