I hear it is now open to 5 visitors at a time. Does anyone know how to get in? Reservations? Get in line?
First you have to buy your Forum-Palatine-Colosseum pass for 11 Euros, then climb up Palatine Hill and head for Circo Massimo... wind to your right as you'll see signs directing you to House of Augustus.
There were no "reservations" in March when we went (shortly after opening) ... just get in line and wait your turn - Incredible and well worth the wait!
