I did my EASA PPL in San Diego and decided to do hour building in the same region since I was already pretty familiar with that environment. I looked around a lot before deciding and in the end decided to become a member with Plus One Flyers (
http://www.plusoneflyers.org/), who run ops at four different fields in the San Diego area. They do not own their own aircraft, rather individuals rent their planes through them using their platform.
There are a ton of different planes. I choose a great, newly refurbished PA28 Archer (180hp) with a Garmin 430 stack, digital fuel monitoring, etc. The price was 115 USD (wet) per hour and I managed to squeeze that down by 10% agreeing to fly at least 50 hours in my month. In the end I logged close to 90 hours in that time, flying to some great locations (Las Vegas, Phoenix, San Francisco, Los Angeles...).
The One Plus organisation is very professional, they even have on-call instructors around the clock that you call if you have any questions regarding safety. You pay 30 USD a month for membership.
I had a EASA PPL and did some paperwork through the FAA website. I booked a meeting at the local FAA office and did a very brief interview with them, basically to check that my language skills was proper enough. I then got a 90-day paper slip (and my FAA card was sent to my adress in Sweden a few weeks later). This license is a piggyback-type, meaning that I have to have a valid EASA at all times to back it up.
I came back after a month, a much better pilot thanks to the challenging environment (Class B, a lot of traffic) and the amazing scenery.
Here's a video summing up that month of flying:
