I typically drive myself to PHX and park off site but on trips more than 1 week it makes financial sense to use this service from my home. They will pick you up from your far away location (mine is San Tan Valley) at whatever hour you need. If you choose the 'group van' expect some extra time because they will pick up others. Pickup at the airport was easy as they have a stand outside (Terminal 4 anyway) plus an App for your phone that gives your van location and a way to contact the driver...save your friends and relatives the aggrivation of navigating one of Americas busiest airports.
