Travel Note
The drive from San Diego / Inland Empire is about a 15 hour commute with stops. It's a long way to go but is definitely achievable all in one day. The more drivers you have, the better! A good half way point if you chose to break it up into 2 days would be staying right outside of the bay area, along Interstate 580.
Flight
Flying you have several options: Option 1 - DRIVE up to Oakland, then take Contour Airlines from Oakland directly into Crescent City on a smaller plane. Option 2 - FLY into Oakland, then take Contour Airlines directly into Crescent City. Option 3 - FLY into Medford, OR and rent a car to finish commute into Crescent City. It's about a 2 hour drive. *Note - there is only one flight in and one flight out of Crescent City each day.
House Or Rental
Staying in a vacation rental or an Airbnb is a great option as there are several beautiful properties to choose from and if multiple people are needing rooms it can be the most cost effective as well.
Hotel
Oceanfront Lodge has beautiful views of the ccean and Lighthouse and is just a few minutes away from the wedding location.
