Welcome to the RTA Forum!

This doesn't sound like much of a roadtrip, so it doesn't seem like the kind of trip we'll be able to provide much help with. Medical Tourism is pretty much the biggest reason people travel to Mexicali. If I were in your shoes, I'd probably contact your travel company to see what suggestions they have - being that they are already booking everything else for your trip and will have a better idea of what is possible considering your medical concerns - and perhaps also contact the area's tourism board.
