United Terminal 2b Heathrow to rideshare or train terminal

Fascinating that most resources only describe the walk as length of time rather than distance. I'll usually make the walk from the Elizabeth Line to Terminal 2 in about 10-15 minutes, and my walking pace is a 12 minute half mile. Take that as you will.

According to Uber the pick up point is in the short term car park. Level 4 row H. If that’s the car park I’m thinking of it’s right outside the terminal and likely to be a much shorter walk. I can walk over to the Elizabeth Line station in about 10 minutes. The Underground station for the Piccadilly line is about 3 to 5 minutes closer. I think the central bus station is there too.

I know this area very well. The rideshare and car service pickup area at Terminal 2 is in the car park on the arrivals level. If your friend sees signs for the Hilton Garden Inn, she can't miss the pickup area. She would actually have to walk through it to get to the hotel. It's about a one minute walk after exiting the terminal and it's covered.

For the Ellizabeth line, it's about a 5-7 minutes walk. She would have to take either the elevators or the escalators down to the lower level and then walk towards Terminal 3 for the Elizabeth Line. (Even though they are much more crowded, the elevators are easier because there are actually two sets of escalators not next to each other she would need to take to get to the lower level.)

Once down at the lower level, she will first pass the entrance to the Underground and then find the combined entrance to the Ellizabeth Line and Heathrow Express.

The rideshare area is much closer and easier as it is literally on the same level she arrives.

I was literally there four weeks ago and walked to all those areas. I've also done this many times.

Maybe the unmentioned first question is where is your friend going to? What Hotel?

Reducing steps on the front end is of little use if you just add them, or more on the other end, or in making changes (as in from the Elizabeth Line to another mode, or at a station with lots of steps)

As someone mentioned, your options are many, black cab, rideshare, Piccadilly Line, Elizabeth Line, Heathrow Express, Express Bus, private cars...

Thank you for the responses!
She will be staying in Kensington, visiting her daughter/SIL and their newborn daughter, who will be coming in from the North of England. I think the black taxis are a lot of fun.

If going to Kensington, then the Elizabeth Line is entirely the wrong route, it is the Piccadilly line tube train, straight to Kensington.

Where she is going is important in regards to public transportation.

If a black cab (the most expensive way) or a rideshare like Uber, or a pre-arranged car hire, she will be dropped off at her destination so it doesn't matter where she is going except when it comes to cost.

If she's looking to take publlic transportation, then where she is going in Kensington is important. Kensington is a large area and which area of Kensington she is going is important.

If the heart of Kensington, then the Piccadilly line plus a transfer to a District Line train would be necessary (High Street Kensington.) If to South Kensington, then the Piccadilly Line would be taken alone.

However, getting back to her issue with walking, I would suggest the first option of some kind of hired vehicle and driver. Or, if she wanted to save some money, take the Elizabeth Line to Paddington and from there get a black cab or Uber to her final destination. There are no taxi stands outside of most tube stations but there is one at Paddington train station. It's not far from the tracks used by the Elizabeth Line and Heathrow Express.

We also need to consider luggage. Will she have a great deal and can she handle it by herself. If she's fine with luggage, then any mode of transportation is fine. If she will need help, I would then suggest the private car--taxi, Uber, car hire.

If she is looking to arrange for car and driver ahead of time--this is less expensive than a taxi--then a couple of companies suggested on this forum are Blackberry Cars and Just Airports

I think that a private hire car would be better than Uber for her. The driver will meet her at Arrivals as she comes out and take to the car helping her with her bags. That gives her some help and takes away the effort and anxiety of finding either the Uber pick up point or the right train or tube.

Another thing to think about is assistance from the gate to the entrance to the terminal. Heathrow uses large golf carts to transfer people rather than just wheelchairs. If your friend has that much of a problem walking,she could request assistance.

Oh, and remind her she needs to get an ETA prior to departure.

making sure to use the link just above from Frank II - she doesn't need to waste money on intermediaries who do nothing more than she can do for herself and then charge a lot of money for doing nothing more than she (or you) can.

Thank you for your kind replies. The cheapest options that don't require much walking fit the bill. Private car to arrival gate to the front door is probably the best bet. Around London, what would you recommend? Taxi or Uber? Some of the Tube stations seems to have a lot of walking internally. Once in London, she will be with her daughter, SIL, and her newborn granddaughter, so the pram also comes into the picture.
