Good news! I was able to change the time of the shuttle so I get almost an extra hour sleep AND I tested the alarm on my cell phone. It is really loud! I depart Havasu at 6:00 am for the 3 hour trip. There is a potty break in Searchlight, then drop off at the Las Vegas airport. I am soaking up some nice warm sun right now since I understand it is not what I will get when I am home.
