Hello July,

Generally speaking, the expressions "no wonder", "small wonder" and "no small wonder" all mean the same thing. They are all used to indicate that something is not surprising or that something is hardly surprising.

Perhaps "no small wonder" was used with a more literal meaning in this sentence, rather than the usual idiomatic meaning.

'It's no wonder' would mean that it's obvious, or very easy to see why, or no surprise that you got him to go.

'It's no small wonder' means that it's a big deal, very surprising, or a big accomplishment that you got him to go.
