I've passed by it last Sunday and even if I didn't pay enough attention, I'd say that it's like 1/4 covered by scaffoldings, so you should have plenty of stuff to look or take pictures without framing anything bad.
On the bright side, the restored part is glowing!
I was amazed, because I was totally used to see it covered by dirt and smog, and I guess that in 30 years this was the first time I've seen it that clean.
EDIT: I'd add that from outside I could see lots of people inside, so I guess if it's in your plans you should be fine.
Oh thank goodness. ;_; Seriously, I would have been crushed. Phew.
Excited for tomorrow! Ancient Rome Day.
