Slovenia without a car - 6 days

Hello

I will be traveling to Slovenia (and Croatia) in September

I planned to spend 3 days in Bohinj/Bled and then go to Bovec for 2 days

How difficult is it to get to Bovec without a car? After Bovec, I plan to go to Zagreb (also with public transport)

The general idea was to wake up in Bled on the 14th and go to Bovec and stay there until the 16th when I'd make my way to Zagreb.

Does anyone have any tips on either stretch?
