What type of things do you two like to do besides be outside and beaches?
Laguna Beach Top of the world is a pretty view. You can also access Aliso Wood Canyon wilderness park from there.
You can go to Whiting Ranch and hike to Red Rock Canyon.
Kind of like Cars Land at CA Adventure
What type of food are you curious to try? Orange county has a lot of new restaurants that are chef owned and quite delicious.
San Clemente Cars and Coffee is fun. There's a group that leaves Santa Ana. They are fun to follow as they are super cars playing with each other on the freeway.
Fashion Island is a high end outdoor mall. Irvine Spectrum, outdoor mall, just opened up Fogo De Chao which is a nice Brazilian Steakhouse.
DM me if you have some specifics. I can give you the run down of different things to check out. Have fun at Disneyland! My family loves it there.
