Hello everyone,
There had been some interest in Vatican Tours around the same time I was going (Around August), and thought I'd share what I've found. Since it has helped me personally make my decision.
Early morning tours don't seem to be a thing anymore. Tour groups enter the same time general admittance does. The special tunnels/routes they use no longer apply, they go through the same routes general admittance does (i.e. no more directly to the Basilica). The routes are now designated, so its not like Tour guides can take you to anything special anymore (you're all walking in the same direction, the same route). You cannot buy tickets at the door, you have to buy them ahead of time. Additionally, it appears in August, the crowds are substantially less (i.e. those nightmare crowds are no longer a thing in August), not to mention I'm sure they have limited tickets they sell due to Covid, so crowds should be even less of a factor (and from my conversations with locals, there aren't many people visiting the Vatican to being with now a days). I.E. Crowds are not a factor either.
In short, all a Tour guide does now is offer you context to the exhibits you will be seeing. Personally, considering most tours start at around 70 dollars, and the tickets themselves are 17 euros, I will be buying the tickets and going on my own. I care more to visually see them than get the historical context behind the paintings, building, etc. Personal choice at the end of the day, but thought I'd share what I've learned so far.
