LAX. There's no public transit from LAX, so either rent a car or Uber from there.
It is optional, but it'd be great to see all of you there! It'll be a fun day.
It has 3 bedrooms and fits up to 8-10 people. It comes out to approx. $250 per bedroom per night. If you want to socialize with other guests, then this is better than staying in your own hotel room.
Very likely, Yes, LA is very spread out. If you plan to have a beach vacation and only stay in Sunset Beach, then you can get around by Uber. Total cost might be about same or more with Uber, but if you don't want the headache of a car, you might be able to get by without one.
Of course! Just let us know and we can arrange something. There might be accommodation available.
We are planning a road trip to leave LA from Wed Aug 6 to Sunday Aug 10 to visit Yosemite and also Sequoia National Park. We'll be staying in an Airbnb near the park. If you are interested in joining, let Edmond know. The more the merrier.
