To the OP I’m very sorry you had to deal with so many issues not of your making. I also hope your aunt recovers. So, so stressful. I don’t give Princess a pass that their employees are new and don’t know how to handle situations like this. That’s ridiculous! I’m sick and tired of covid as an excuse for poor service. Emergencies such as this occur on a regular basis on cruise ships. The restart of cruising was a year ago, plenty of time to get their ducks in a row. They should have contacted more senior officers if they didn’t personally know how to handle this situation. Pre-covid we have friends who had an emergency situation similar to your aunt’s. Princess assisted the spouse every step of the way. Helping with luggage, accommodations, transfers etc. I’m appalled to read about their lack of sensitivity and assistance in your case.
As to the medical charges, the only people I would feel obligated to pay their medical expenses are my spouse and minor/dependent children. I would have told Princess it’s their problem not mine. THEY are the ones who should have made sure the aunt had enough credit to cover unexpected expenses onboard. I would notify my credit card that this was a fraudulent charge and I did not authorize it.
We have cruised Princess since 2002 and overall have had good experiences. It makes be profoundly sad to see Princess steering itself into the reef so to speak. I will be elite after my next cruise in September. Even with the gradual diminishing of the product, pre-covid Princess was still pretty good. Not so sure anymore.
