History of San Diego in a few lines:
Origins:
San Diego was inhabited for thousands of years by indigenous peoples, especially the Kumeyaay, before the arrival of Europeans.
Middle Ages:
During the European Middle Ages, the region remained indigenous territory, with organized societies and local trade without contact with the outside world.
19th Century:
The area passed from Spanish to Mexican control after independence and later to American control in 1848 with the Treaty of Guadalupe Hidalgo. From then on, its urban and military development began.
Present:
San Diego is a large coastal city known for its mild climate, naval base, technological innovation, and cultural mix near the Mexican border.
We loved the city and feel like there's so much more to see. We were told it was a very unsafe city, but we didn't get that impression at all. The streets are clean and beautifully decorated.
San Diego goes very well with Los Angeles because of the proximity, the relaxed climate and the easy coastal routes between them, and with San Francisco because it is often the perfect starting or ending point of a complete West Coast route linking cities, beaches and natural parks.
Hotel: Rodeway Inn San Diego Near Qualcomm Stadium €88, 1 night for 2 people with a pretty good breakfast and a pool (we didn't have the opportunity to try it).
Extra-large and comfortable bed. It's not an idyllic spot, but it's fine for sleeping and going to bed early. (The last sentence appears to be a separate, unrelated comment and has been omitted.) Booking.
Information obtained from the web https://www.exteriores.gob.es

Return ticket: You must present a return ticket dated within 90 days to prove that you will leave the country within that time.
Travel insurance: It is recommended to have adequate travel insurance due to the high cost of medical care in the USA. In our case, we always used Iati, but lately we've been using Globalfine, which is much cheaper.
Vaccines: There are no mandatory vaccinations for entry.
Special conditions: If you have traveled to certain countries, such as Cuba, Iran, or Syria, after specific dates, you may need a visa instead of an ESTA.
International driving permit: It is requested through the website of the DGT.
It costs €10.51. The good thing is you can order it online and pick it up without an appointment. It took a couple of days for ours, then you go to pick it up and it's a cardboard card like the ones they had 20 years ago.
Travel insurance: It is recommended to have road insuranceHeh. The best known and most complete ones are Iati y Heymondo, if we don't need insuranceWe'll grab him with... oh fat Globalfine which is much cheaper, in this case we use Iati.
Payment card/currency exchange: we always go with Revolut definitely.
