I copied this info from somewhere but I just can't remember where. I have that the shuttle leaves HRH at 8:15 am, 9:30 am, 10:40 am and 12:00 pm. and that it leaves Sea World at 4:25 pm and 7:00 pm and wet and wild at 4:40 pm and 6:45 pm. I think Sea World is open until 10:00 right now so hopefully there is also a later shuttle. We leave next Saturday and are planning to use the shuttle as well. Hope this helps.
