June vs. July

[mscoryb]

I'm trying to decide between a late June or a mid-to-late July trip for 2015. Is there any difference in crowd levels or weather over the summer months? What would you choose?

We've gone during both and in our experience it's about the same. This year in June the parks were almost completely absent of the large Brazilian tour groups. I think that might have had something to do with the World Cup though, because I seem to remember them being there in June a few years back.
