Travelling can be stressful at the best of times!
Have you had a look in your Junk folder to see if it has been sent there by your provider?
Also, you can fill in the passenger locator form
within 72 hours of arrival so there is plenty of time to do the form again, maybe wait until Thursday to try again if the email receipt doesn't come through by then.
On the lighter side, what have you planned to see and do during your time with us, we would love to hear?
