First Timer in Croatia

Hi there, traveling to Croatia for about a week the end of June/early July. We’re starting in Split and I’d like to book a private boat tour to take us to explore Hvar and maybe the neighboring islands. I can’t swim so really just looking to enjoy cruising and taking in the scenery. Any recs?

Also would like to do a few day trips but prefer private transfers (yes I know it’s more expensive but it’s personal preference). Does anyone have a company they absolutely recommend? See below for where we have in mind

1. Split to Plitvice National Park (day trip w/return)
   
2. Split to Mostar to Dubrovnik
   
3. Dubrovnik to Kotor & Perast in Montenegro (day trip w/return)

Thanks in advance!
