LAS to Henderson (Ravella)

Hi - my 82 y/o parents are arriving in Las Vegas tomorrow at 1:35 and need to get to the Ravella. I called the hotel and the shuttle leaves every three hours, starting at 10:30 am. This means they will miss the 1:30 pm shuttle after getting their luggage etc. They will not want to wait two hours for the next shuttle.

I need info on how to get them to the Ravella without (hopefully) paying a $75 cab fair. Any insight out there would be greatly appreciated! Thanks! I want to get this arranged for them before they fly out....
