We understand this is a destination wedding and travel and lodging can be expensive. We do have some suggestions of where to stay in and around Paso Robles.
There are many hotels to book in the area, ranging from normal prices to the more extravagant. We have stayed at the Best Western Black Oak and recommend it!
The area hosts a ton of vacation rental options as well! We’ve stayed at many places through Airbnb, Vrbo and Vacasa. Templeton is a town just south of Paso and good spot to check for Airbnb’s.
