Are you looking to stay right in the vacinity? What about having dogs with you? How are you travelling down, car, coach, train? Its really in the South Kensington area of London. Sorry makes a big difference if you have a car or not for different reasons.
Earls Court is on the west side of the centre of London (you can easily find it on Google maps), well within the congestion zone. Transport links are excellent, so there's no need to stay nearby.
We are in a car with one dog. Guess we dont have to stay too close as long as not a huge drive on the morning . We are coming down from SKC and couldnt face a long drive the next day.
I think there is a travel lodge type place at the bottom of the M1. Earls Court is only about a 20 drive from there. How brave of you to do Gundog Breeds & Disc Dogs, I would love to do both but dont think I'm up to it lol
