Where the sources are unclear.

Event-count threshold: the ST-50 form says sellers at 3 or more shows a year must register for a permanent account, while Virginia Tax's festival-season vendor tips page (https://www.tax.virginia.gov/news/vendor-tips-fall-festival-season) says sellers at 3 or fewer events can use ST-50 and sellers at more than 3 events must register. Confirm with Virginia Tax at (804) 367-8037.
A 1992 Virginia Tax Commissioner ruling (https://www.tax.virginia.gov/laws-rules-decisions/rulings-tax-commissioner/92-91) says an event organizer may obtain a single temporary sales tax registration covering all sellers at the event; this is an option, not a requirement, and the ruling is old, so confirm with Virginia Tax.
Herndon's event pages are written for the Town's downtown event spaces; the Temporary Use Permit PDF they list was not read, and the Town did not publish a temporary business license fee on the pages read. Ask Town Events and Revenue Services (revenue@herndon-va.gov).
