I'm not sure how you can avoid crowds and sick people, even with a GAC. I won't pretend to offer medical advice. Others have already given free advice, most worth what they charged.
You might want to check with your doctor and ask if the trip is a good idea. I'd be afraid the GAC may give you a false idea as to how much exposure you're really avoiding.
