Hello @Pam Burke,
We use the "+ Trick" all the time during testing all the different paths.
I wanted to mention if you need to have someone who is not an account user or test user in your system you can go through the steps of Perform Test "Test the event myself" and when the new tab opens you can copy that URL and send it to whomever you need to test a registration as well.
I believe we get 100 test per event.
