It seems to work in Manchester because I think they charge a fee to park there? But they are also on the perimeter of the taxiway so out of the way of the terminal. I don't mind paying for entrance to a nice viewing area, and buying refreshments whilst there in order to help with its' upkeep.
In the meantime, I guess for Heathrow it'll have to be Myrtle Avenue or the Premier Inn on Bath Road, away from the hustle and bustle of a busy airport terminal. And then the kids can enjoy the terminal experience when we actually go on holiday
