Early in the episode, Joan Carter drops her daughter off at school. As she pulls away from the curb, a crewman holding a large reflective panel over his head is mirrored in the rear driver's side windows of the station wagon she is driving.
When McGarrett is on his way to Sea Life Park, immediately before he pulls into the parking lot he is seen driving behind the Ilikai Hotel. Behind the Ilikai is a parking lot for the marina and dead ends. Also, the hotel is in Waikiki and Sea Life Park is in Waimanalo, a good half hour drive away.
