Ditch restrictive EA/ED at highly rejective schools unless you have a hook. Instead, apply EA to schools you would be happy to attend, offer merit, and you have a good shot at getting in. Your mental health will thank you if you have an early acceptance you are happy about. And you will be able to pare down the RD applications you need to submit. You can still apply ED2 to some great schools, to boot.
The admissions rate for RD at highly rejective schools isn’t all that different than ED for the unhooked masses - they are both abysmally low. If you are unhooked and in love with a school isn’t super rejective, maybe ED1 makes sense. But other than that, the disappointment of early rejection is a huge stressor and could send you into a huge, unnecessary panic of last minute research and more applications than you really need.
ETA: big trips to visit lots of campuses aren’t essential for all kids. Ask “is there something I can learn that would change my mind about applying to school X”. If you are going to apply to a super elite school no matter what, save the trip for when you get in.
Also, kids grow and change a lot between junior and senior year. Schools they think they want spring break junior year may be completely irrelevant by spring senior year. Be open to evolving- which is another argument against ED1.
