Will previous French make learning Spanish easier/faster?

I took 3 years of high-school French but that was 40 years ago. Since then I’ve made two trips to France, one to Belgium and two to Montreal. Outside those brief stays, I’ve had no opportunity to use my French, so it is terribly rusty now. I’m wondering if anyone else has tried to learn a second Romance language after learning a first. Does it tend to get confused and make the third language more difficult than the second, or are their Latin roots similar enough that one builds on the other.
