GETTING AROUND VENICE

BEST WAY TO GET FROM AIRPORT TO HOTEL, TAXIE? WHAT ABOUT THE GONDOLAS? IS IT SAFE TO WALK THE STREETS? WHERE CAN I GET A MAP OF THE AREA IN ORDER TO GET AROUND? NEVER BEEN THERE AND WANT TO SEE EVERYTHING THERE IS TO SEE AND TRY ALL THE WONDERFUL FOODS. GLAD TO HEAR FROM ANYONE THAT WANTS TO ANSWER. THANKS HARVEY
