Status update on my LA -> SD -> LV -> LA trip this weekend.
LA->SD (Fri 1/17): I stayed at Hotel La Jolla which had 2 blink chargers. I was charging at 10mi/hr and was able to get enough charge by the morning. Blink cost for me was $1/hr and the hotel valet rate was $14/day. Before arriving at the hotel, I was a bit worried due to the history of Blink chargers melting and getting recalled so I had a plan b and plan c. Plan B - I called SD Service Center the day before asking if I could come in to charge if needed Saturday morning, and they said sure, swing on by, they open at 8am. Plan C - Was a person on plugshare that lived nearby my hotel.
SD->LV (Sat 1/18): First time going to Barstow Superchargers, wasn't sure what to expect. I arrived and bays 1A and 1B were occupied and I pulled into 2A to fill up while we grabbed some lunch at the Chili's. When we finished, my car was the only one so it wasn't crowded at all. Going to LV, I had some ideas lined up on where I could get charge based on this thread. We stayed at the Trump International Hotel which is valet only. When I dropped off my car, just asked them about charging and low and behold, they have an outlet with NEMA 14-50 connectors. Sweet! Valet was able to get the UMC out of my trunk and plug in overnight for 25mi/hr charge while I was there. I asked them how often they see Model S's and they said currently about once a month. One time they did get 3 at once, but the owners were able to switch off between themselves since there's only one NEMA 14-50 outlet and another 110V.
LV->LA (Mon 1/20): Pretty uneventful back home. However, when at the Barstow Superchargers, a couple pulled into the 1B spot while I was finishing up at the 1A spot (no one else was there). I went over to talk to them and let them know about the two chargers being shared between the 4 stations setup and how 1A/1B were on one and 2A/2B were on the other one. When I unplugged, they were still getting a low rate of charge so I told them to unplug and replug and I think that worked. Barstow -> LA is pretty awesome, I typically average in the mid 300W/mi but on that drive, I got 250W/mi due to all the downhill.
