Normally when I travel to the UK from the US I'll take the tube to my hotel. According to https://www.gov.uk/guidance/how-to-quarantine-when-you-arrive-in-england#new-rules-for-fully-vaccinated-arrivals however, you'll need to quarantine until you get the test results.
If I could get tested at the airport (Heathrow) and get a negative result within an hour or so that wouldn't be too disruptive to my routine but I'm not seeing anything like that on the scheduling website.
Skimming over the test providers a lot of them let you self swab but you have to snail mail your results, so it could very well be days before you get your results back. So how are you supposed to get to the hotel while awaiting the results? Can I do the tube or do I need to do a taxi?
Also, what about food? The hotel I usually stay at doesn't have room service. I guess I'll just have to do Uber Eats or whatever until I get the test results back?
