I'm going to ask for a little help tonight. Does the following sentence have double negatives, misplaced or dangling modifiers?

Question

"I left my agenda in a restaurant which had all my important dates in it."

Answer 1

There are no negatives -- so that rules that out.

Do you see the misplaced modifier?

Answer 2

Yes, I found it. It was, "all my important dates in it."

Next question. Does this sentence have
double negatives, and how can I revise it?

"In my experience, performing in front of a crowd is not hardly as daunting as it seems."

Answer 3

The entire misplaced modifier is "which had all my important dates in it."

Yes, the second sentence has a double negative -- "not hardly." Just omit one of those words.
. . . is not as daunting as . . .
or
. . . is hardly as daunting as . . .
