To stay: We always travel with www.airbnb.com. On this site you choose if you want the entire apartment/house for yourself or just a room. You have places at a very good price (sometimes they are the same or cheaper than a hostel). In addition to staying in a place like your home, in general everything is super clean.
Other useful APPS: YELP and TRIPOSO. In the latter you do not need Wi-Fi (only at the beginning to download it and download the city you want). Once this is done, you don't need to be connected to look at it and it gives you tips for the city where you are, including different items.
The first is a search engine, where you do have to be connected to navigate, and you can search through different filters for your places of interest. It includes reviews. You will find everything, from restaurants to laundries... whatever.
BE CAREFUL with the parking... read the signs CAREFULLY. On the West Coast it is very difficult to park, each block has its regulations. Read well what days and at what times you can parl. Sometimes it is convenient to leave it in parking lot. There are some cheap ones and it ends out being cheaper than the insurance fine.
In Santa Monica, for example, at night only residents with a sign can park and only in the blocks that the sign details.
Parking meters: In theory from 6:00 p.m. to 6:00 a.m. they do not work, that is, you can avoid. paying the ticket... But check out at the moment just in case.
ATMs in Las Vegas: avoid withdrawing money from the ATMs that are in the casinos. They charge extra fees for each extraction.
WE DEFINITELY RECOMMEND THIS WEST COAST ROADTRIP FROM END TO END.
