Let’s see if we can help the OP (a reasonably novice rider) plan his own 14 day holiday.
I asked Kurviger for a non-motorway, reasonably twisty route of Calais > Ulm > Zadar.
I chose Calais, as I guess you’ll start from London? I chose Ulm, but only because its location gives a reasonably straight line between Calais and Zadar. I chose Zadar, as it’s in Crostia and is a reasonably popular destination.
Kurviger gave this route:

It is 1,200 miles.
I then asked Kurviger for an alternative, non-motorway route between Calais, Ulm and Zadar. This was 100 miles shorter:

I then asked Kurviger for the same Calais, Ulm, Zadar route, but using motorways. This is a pretty similar distance at 1,100 miles.

You want to spend three to four days in Croatia and have a total holiday period of 14 days, door-to-door. That (assuming you have no days off the bike anywhere) leaves a minimum of 10 days for the round trip London > Zadar > London. Gain a single day, if you cut your time in Croatia down to three days, obviously.
Let’s divide those 10 days evenly, splitting them five for the way down and five for the way back. The intermediate, non-motorway distance is 1,100 miles between Calais and London. That is an average of 220 non-motorway miles a day, for five days. It is the same for the way back. You will also have to add the nearly 100 miles on day one to go from London to Calais and the same 100 miles on day 14, too.
That lot, including the screen shots and tapping the post out, all using nothing more than an iPad, took me no more than 10 minutes.
Now, YOU know YOU, way better than we know YOU.
A. Can YOU do 210 miles a day on non-motorway roads for five days on the bounce, one day after another?
B. Can YOU then do four days in Croatia, your chosen holiday destination?
C. Can YOU do the same 210 miles back for five days?
All without a break / day off.
That is just basic sums but it gives you an idea as to how to start planning return trips of over 2,000 miles…… and you are asking people where to stay, what to do etc etc etc. Now you maybe see the problem? This is all before you even start riding around for four days in Croatia, which you also want to be told what to do.
Come on, make an effort……
A. Start with something as simple as asking Google to give you suggestions for Calais to Zadar. Then ask ViaMichelin for its suggestions for the same journey.
B. I have given you the basic Kurviger suggestions. They are only suggestions, I really haven’t looked too hard at them.
C. Look at the distances and look at your time available.
D. Do the very simple sums, based on what YOU can or want to do, riding wise.
Can it be done in 14 days, door-to-door, using non-motorway routes, with no days off? Yes. Can YOU do it? Who knows?
Do some planning for yourself and come back with your ideas, please. Or just ask Simon Weir…….
Just for fun, I did ask ViaMichelin for its fastest, non-motorway, motorbike, suggestion:
It is that easy to do. Naturally enough, it is still over 1,000 miles.
