Does this Ronald McDonald House have a private suite for an immune suppressed child?

They have a small separate family suite. Call to see if that can work for you.

They have a small suite that may be used for that purpose, but you need to call them and see what they can do. I'm just a volunteer.

What Sandee said, it's all about availability, the older rooms on the facility 300 and 400 offer much more private rooms. And less families up to 8 in each building, and would probably work well for your family
