Just back from Adriatic Treasures. Excellent adventure. Absolutely beautiful region. glad we chose land trip over small ship to visit inland cities and wineries. FYI stuff: early June and already rather warm. only caves required jeans and sweater. no need for sport coat or any dressy attire at all. good walking shoes a must. Dubrovnik - walking the wall before tour a must do. bring your voltage convertor / adapter. Rovinj hotel beyond amazing. nobody will starve on this trip. stay COVID safe - risk down now, but for crowded indoor venues be smart. Use your free time to explore towns as all very safe. enjoy this gem !
