It has been a while since I have been anywhere alone. It felt very weird going to the airport by myself and boarding the plane.
The only hiccup I encountered was my rental car. I searched for “San Diego Airport” but didn’t confirm so it gave me a pickup at another location in San Diego. It wasn’t a problem. They still had cars available and rented me one, although this one didn’t have GPS and being as directionally challenged as I am, I had to use my phone. It took a little getting use to, but I eventually got the hang of it although I did miss seeing the route on the dash.
For my room I booked an Airbnb. It was my first time using one even though I have stayed in many Home-Stays around the world through the years before Airbnb was a thing. It was a little hard to find, but once I did the host was friendly and the place was incredibly clean. I have always had good luck with home stays and have found it to be a more authentic experience to see how the locals do it. Although you are not on “hotel row” you will find that things are cheaper when catering to locals rather than tourists. I love hole in the wall places to eat with good prices and awesome food. Staying in places like this is the best way to find the off the beaten path places that the locals frequent.
