SLO County Regional Airport is probably the easiest/ closest option to fly into, if you are flying in from out of town.

LAX or Santa Barbara would be your next best option but would require you to rent a car.

-SLO County Regional Airport (SBP): 3 miles to Downtown SLO

- Los Angeles International Airport (LAX): 189 miles from Downtown SLO

- Santa Barbara (SBA): 95 miles from Downtown SLO

Most hotels in downtown SLO are within walking distance to the wedding venue. So for any other weekend activities an Uber/Lyft would suffice.
