I would reframe the way you’re thinking about these highly rejective programs. Much like HYPSM admissions, the default should be to assume you wouldn’t be accepted. You’re in very good company with many high achieving high schoolers who will all go on to do amazing things even though they weren’t chosen for an elite summer program.
I would approach your parents “since I wasn’t accepted to any of the summer research programs, I need to come up with plan B. I was thinking about getting a job (or X, Y, Z). Is it too late to add me to our family trip?"
