I’m excited but also confused

1st time Europe Trip and Honeymoon

I am planning our honeymoon from NY to Europe and want to visit the following countries in this order.

1 London
2 Paris
3 Amsterdam (maybe)
4 Germany (Rhine Valley)
5 Switzerland
6 Austria (Austrian Tirol & Innsbruck)
7 Italy (Venice, Florence, & Rome)

Should I change the order of the countries to minimize travel time? How would I be able to save money travelling through all of these countries?
