Thank you! Yes, your previous post has been very helpful and I am still referencing it now- much appreciated.

My concern now is that the other family we are traveling with may not have all of their documentation (PCR results, specifically) before 48 hour window to start submission. I have all documentation for my family ready to go. We travel Monday. Because of external timing issues, the best window for me to fill out for my 4 family members is this evening. So I am wondering if it is wiser to just do the submission for my family tonight and have other family do their submission when they are ready and use same email/phone. Just not sure if that will confuse the system.

Sorry if I am missing an obvious solution...
