Since I use Verizon card, wifi is not as important. My observation of CRC v.s. PC is :
1. LAX CRC is bigger than LAX PC with more bathrooms.
2. Free shoe shine at some CRC (SLC).
3. Better wine at CRC. LAX PC serves two bucks chuck. It's pretty sad. CRC also serves Mojitos, not at PC.
4. Better snacks. CRC serves premium nut mix and they change their snacks through out the day.
5. CRC has a quite area with no cell phones allowed. ^
