Here's a general map of the free buses with hotels marked. I'm convinced a lot of these would be quicker than the times specified in the article.

Taking the Hilton Garden Inn as an example - obviously if you're flying into Heathrow you can get the tube from the terminals directly to Hatton Cross. You'll have to pay for this of course. 10 mins from T5 and five mins from T2/3, followed by a short five minute walk to the hotel.
Alternatively you can get free buses. From T5, you can get the 423 bus which runs along Bath Road, round the eastern perimeter and drops you at the bus stop on Envoy Ave next to the hotel. This would take 15-20 mins. Or, you could get the Heathrow Express for free from T5 to Heathrow Central (five mins), and then get the 285 bus which runs along Bath Road (10 mins), and again, drops you outside the hotel. All free.
If for some reason you want to take the southern route, the 482 and 490 buses run from T5, to T4, to Hatton Cross station. Maybe 15 mins journey time. Then a short five minute walk to the hotel. Again, free.
Obviously this map doesn't mention the bus to the Hilton T5 as it's not in the Free Travel Zone but the point I'm making is that there are cheaper and quicker ways of getting to these hotels if you know where to look!
For example, if you're staying at The Travelodge Heathrow Central (a favourite because it's so cheap) or the Doubletree Heathrow, although these are outside the free zone you can still get the 105 and 111 buses from Heathrow Central and they will drop you very near to both hotels for £1.50. This is a far better option than the Hoppa buses.
