Hello do you mind sharing details of your transportation from airport .. such as taxis , Ubers? What is available to get to the port from London airport?
We used pink berry car service they will pick you up from Heathrow and take you to the port,they will also take you sightseeing as well but you have to schedule with them. We flew into Heathrow outside of London. About 230 pounds for 2 people round trip
