Second Trip to Europe

Thing is I want to do an eurotrip.

dates would be from March 20 through April 10

countries I’m including in this trip are France Switzerland, and Germany. March is my wife’s birthday BTW and I want it to make sure is a good time to go you know.

also How many days for a first time to be in these countries?

i was wondering Maybe doing 5 days germany 5 days France and 5 days in switzerland to fully see or hust to cover the mainhighlights

about the budget no need to worry about it I can cover everything as long as you know hotels adventures activities is not tight.

I was planning to start maybe from France then heading to Germany and then Switzerland were departing from LAX
