After making a few other trips since the last WoMo trip in 2015 to France, we went to Croatia in 2019 with a WoMo from our trusted rental company. Planned was a coastal tour from the northernmost part of Croatia to.....(as far as we get without stress).
We had thought that it would certainly not be so hot in June, until the first days of July, but far from it. Conclusion: our own ordered WoMo has air conditioning 
A very nice trip, which will certainly not be the last to this area. Especially the trips into the hinterland were great!
