Transfer trauma

Today was a day at sea. For reasons I won't go into my private transfer from Dover cruise terminal to Heathrow got canceled. I went to Princess to get their $69 transfer. I also checked on-line and earlier flights out of Heathrow than my 4:20 p.m. one were available so I decided to try and stand-by for an earlier flight. But Princess says it is too late to book their transfer. Sounds like an arbitrary rule as it is unlikely they really couldn't add me, they just don't want to since they have already communicated with their ground operator. I've been thinking about whether to escalate it with someone higher up who could likely help me out vs. booking another transfer with a tour of London. Both have pros and cons. I'm not sure which is the preferred route right now. I have another day at sea tomorrow so will continue to work on it then.
