Opting out is not an option if you are trying to reach all the potential clients that may be searching.

In the case of regional searches related to tourism it's hard to know what they are looking for. It's in fact much easier to figure out the searchers you don't want.

If Google's list is accurate then , yes it will take time to enter the negative words, but at least we'll know what impressions we are being shown for.

I somehow doubt that their list is anywhere near complete.

The bottom line is how many impressions increase are we talking about here. If it's only, say, a 5% increase it's not going to have much of an impact. If it's a lot more then we'll have to spend the time to monitor it.
