How should I decide on an in-out when traveling to Italy, England, and France?

I'd like to travel to Italy, England, France, and so on.

I was wondering how to save time and money.

The plan is for about a month.

We have enough time, so we can set a reasonable schedule.

If we travel to these countries, how should we decide on an in-out?
