I'll be ending a cruise in Southampton UK. Looking for a train to Heathrow where I will pick up a rental car. I need a suggestion on which train system is the most convenience. Time is not a factor. It would be nice if it were non stop, but it appears that they are not.
The most important issue is getting to the train station from the port. We can walk if it is a short distance. If not we'll have to do a taxi.
