My native language isn't a Romance language, but I have also spent five years learning Latin in grammar school and for me, learning both the vocabulary and the grammar was hard, hard work. I always assumed that for a native Italian speaking person it would be probably a lot easier.
In Italy if you follow classical studies you learn ancient Greek too (first 2 years of high school), which was definitely harder than latin, but you grock the alphabet in a short time. I seem to recall that more often than not the same word had very different meanings depending on the context, while the grammar was similar to latin (well, of course it's backward...).
This said, I agree that for us a bunch of things are probably easier, simply because a lot of terms map directly to modern words, so the vocabulary is fairly easy to build. We also tend to ignore any pronunciation rule - we just pronounce it phonetically using Italian rules. I understand “real” scholars actually follow different rules, and Anglo people have their own conventions. Also, there is a lot of Latin all around us in inscriptions and names etc, so if it “clicks” you can find a lot of inspiration and practice with no effort.
A better approach to Latin studies would also be interesting, I wish I studied Latin with a method like Lingua Latina per se Illustrata
