A trick is to try to get ship wifi in the terminal. You may need to walk closer towards the ship in the terminal, but it is worth a try. Book the comedy show first on Oasis class! Very limited seating. Liked it in the past where you could book before boarding, but it is a frenzy now to do it at the last minute. Plus many cruisers disregard their check-in time and will get first dibs to book when checking in before their assigned time.
