I'm currently in Rome and enjoying my trip so far. I was thinking of going to Ostia Antica in a couple days and I had a couple questions.
1) Ticket availability seems good, but should I buy online before I leave my hotel or can I just show up and expect there to be tickets available?
2) According to the website, the bag storage is closed (in addition to the cafeteria). Do they allow small bags to be brought onto the site?
