Multiple lessons per week? Is this normal?

I'm talking with a local salsa dancing instructor about taking private lessons. I've taken two months of group lessons but the pace was just too slow. I told the new private instructor that I was interested in taking one class per week, and she mentioned that her students typically do 3 lessons per week, which seems like a lot (and expensive). Is this common? How many lessons per week would you recommend for someone who's essentially a beginner? To me, it feels kind of like a sneaky upsell tactic, but I don't know anything about dancing or lessons so I don't want to blindly follow my gut.
