How long for a complete itinerary?

My son was accepted to Mayo Clinic, and our initial appointment was booked about 6 days ago. We travel in July. Currently there is only one day of appointments in the portal. How long does it typically take for the full itinerary to be completed? Right now if only shows an appointment with an internal medicine doctor, bloodwork, psychiatrist, and overnight pulse oximeter test. My understanding from his doctor at home is he should have several days with different specialists, especially considering all the different things he has going on. But I’m getting a little concerned this is all they have planned for him. If it is, it’s not really worth the travel 🫤
