I was lucky in that Princess gave me the info (positive test result and letter telling me I would be disembarked), so at least I had that. As for the per diem reimbursement, that's totally on Princess' end. I filed a claim online on their site (http://www.princess.com/refund-request:), called Customer Service and asked to be connected to Customer Relations (the next step up). The site form asks for receipts for the meals, but they're not required (per the Princess documents I received when disembarked AND per the CS rep I spoke to. She told me I could upload whatever document I wanted, so I tried uploading the letter they gave me, but nothing worked. SOOOOOO, I emailed the with my problem (customerrelations@princesscruises.com) and then 4 weeks later I spoke with a Customer Relations person named Mrs. Patterson who apologized profusely for the delay and confusion and expedited everything. I had a check 2 weeks later. Bottom line, for th per diem, you DO NOT go through AON, just directly through Princess. I hope this helps, let me know if you need more info/help.
