Dennis, Thanks for sharing. I make this trip a few times per year and I'm planning on using my Model S for all future trips (My first one with the S will be in April). It's great to hear these real world experiences so I know what to expect and can plan accordingly.
This is one of my biggest concerns with road tripping in the Model S. There is a total lack of charging stations at hotels where I would normally stay. My next trip is from SF Bay Area to Disneyland for a few days, then over to Palm Springs for a few days, then back home. There are no hotels in Anaheim that offer any kind of L2 charging. At best you may have a 110 plug, but that is not even guaranteed. I don't need those kind of headaches. So I'm planning on stopping at the Hawthorne super charger before checking into my hotel and doing a max range charge, which should hold me over a for my few days in Anaheim and have enough juice left for the drive to Palm Springs. A hotel charger would save me 60-90 minutes of sitting at Hawthorne with some potentially grumpy kids (does SpaceX offer tours?).
I'm also planning to make a trip to Disneyland from San Jose area and I too could not find any hotels with charging stations or plugs. However, I asked around and found that Hilton has 2 J-type chargers. Also, Disneyland parking lot also has several chargers--not sure what type. I think you just have to ask the attendant. I'm planning to stay at a hotel near by and then park my car at the disneyland parking lot during the day and let it charge all day. and then stop by the SpaceX before heading up the I-5 corridor.
