Flew in to LHR this morning. The Yotel is indeed being used as the arrivals lounge. Seems that you may actually need to follow the web instructions and let the BF Concierge know before you board. I asked at EWR and he put my name, "on the list."

Upon arrival in LHR, the person greeting the flight (whom I thought was the concierge) seemed unsure. When I asked about the arrivals lounge, he said that he, "believed" I should go to the Yotel.

When I arrived at the Yotel (about 10 min later - no lines at immigration - IRIS scanner was not working), a CO rep arrived at the same time with the, "list" of people from the flight who were expected. I was not asked for my BP, just my name, which was checked against the list.

Now... as to the Yotel... I was not at all impressed. In fact, should I plan on traveling BF with my spouse on a redeye, I'd either go to LGW or take a different airline.

What you get at the Yotel:

1. A bed
2. A TV
3. Wired internet (I assume for a fee)
4. A telephone
5. A very, small bathroom, sink shower. Not possible to shower without contacting the shower curtain, and sink.
6. A liquid soap dispenser with a very liquidy soap.
7. 2 towels
8. A glass
9. Dim lighting

There is food, coffee, etc., for the normal charge.
I asked, out of curiosity, as to how long one could remain in the, "room." I was told that the time limit for BF arrivals is 4 hours (although one could pay for more).
Space is extremely limited. The stand for the suitcase can only be used by blocking the door. There is a fold-up table which one needs for toiletries, etc, as there is no way to put anything on or near the sink.

All in all, I think if CO is serious about business travelers, they're going to have to come up with something better. I know this is going to sound sexist, but I believe that most female business travelers would not find the lounge acceptable. Large males would not find the lounge usable.

One other point about LHR arrival - in order to take the Heathrow Express into London it was necessary to take a train to Terminals 1/2/3, then connect to terminal 5 and then board the Heathrow Express. Door-to-door, the Gatwick express is faster than Heathrow Express connecting from Terminal 4.

Note also that I don't understand the second connection as the Heathrow Express stopped at terminals 1/2/3 after leaving terminal 5.
