Based on this there don't seem to be any true luxury hotels in Croatia. The Le Meridien and the Vestibul Palace seem to be the top choices in Split. Since I want to be on the water the Vestibul Palace would be a no go. I also see there is a Radisson Blu in Split that gets decent reviews. I know asking about the Radisson in the Luxury forum is a stretch but I wonder how it compares to the LeM.
