Honeymoon in California- August 2020

Hi all, I am planning to take my future wife to California For 10 days honeymoon in Early August. We are hoping to visit a cool location by the ocean for 3-5 nights to enjoy swimming. Maybe after I will go to a cheaper hotel for the rest of the 10 days period near a metropolitan area like SF, LA or SD. We have around 5k in budget that includes rental car, accommodation, food and maybe visiting Disney or seaWorld. I don’t mind driving between cities and staying at different cities. I am not looking for shopping. I want to rest and enjoy first few days then hustle and move around. Suggestion for locations and specific resorts for first few days will be appreciated.
