Hello Brian,
The seats included with your holiday are unnumbered seats in the upper rows of the arena.
Regarding upgrading, one of my colleagues here at Just You comes from Verona, and she says it isn't a bad idea to upgrade to the numbered steps. The view is slightly better, but the main advantage is that you don't have to get there early to grab the best seats.
That said, you might be happy to get there early so you can make the most of the atmosphere. Hope this helps.
Kind regards,
Olly, your editor
