Getting There:

Hotels on the Riverwalk are very close to the convention Center. Attendees can walk, Uber, Lyft, or Taxi at minimal expense. There is also the River Boat Taxi Service: $5 per ride one-way, $25 for a 3-day pass/unlimited rides. Taxi runs 9am to 9pm so it wouldn’t be an option for the morning commute but would be for evening commute back to hotel.
