I apologize if this is a stupid question. I've looked back through previous posts, and it does seem like there's already a fair amount of questions about this, but I'm pretty overwhelmed by all the variables and all the choices, so I thought I'd ask about our particular circumstances.
We'll be in London later this month. My sister and I will already be there (staying in Fulham -- I think Parsons Green is the nearest tube station). My partner will be flying in and arriving at Gatwick. A few days later my sister will be flying out of Gatwick, and a few days after that my partner and I will be flying out of Gatwick together.
Given our location, can someone recommend the best way to get to and from Gatwick? I've looked at the Gatwick Express, but is there any benefit to that over and above just a regular train? What would be the most affordable option that allows a little flexibility? I'd really like something that doesn't hold us down to a specific time, especially for my partner's arrival, since I don't know how long it will take him to get through customs, etc., after his flight.
Thank you!
