Half the fun of Odaiba is the journey: the driverless Yurikamome monorail glides out from Shimbashi and over the Rainbow Bridge with bay views the whole way. There's also a train option and even a boat - here's how to pick.
Take the Yurikamome out (front row, for the bridge crossing) and consider the Rinkai line or water bus back to vary the trip. A Yurikamome one-day pass is worth it only if you'll hop several stops on the island. Tap an IC card otherwise.
Take the Yurikamome monorail from Shimbashi over the Rainbow Bridge (~15-25 min) for the scenic ride, or the Rinkai line to Tokyo Teleport from the Shibuya/Osaki side. A bay cruise from Asakusa is a slower, scenic alternative.
The Yurikamome for the views - sit at the front for the Rainbow Bridge crossing. Use the Rinkai line if you're coming from the west and want it faster.
