Walking is the best way to experience Venice. So, wear comfortable shoes, keep to the right side in narrow calli, and do not stop on bridges.
You can also take the vaporetto: buy tickets or passes at the boarding station, remember to swipe them, be ready to get on and off, and do not stop in the middle of the deck.
Remember that flooding water is salty and filthy, so wear waterproof boots or walk on the raised platforms. When walking on a crowded platform, do not stop abruptly or try to take pictures: you’ll block everyone behind you!
You can check when the peak of the flooding will be at Tide Centre.
