I'm going to London in a couple of weeks and me and my sister are arriving at different airports (Luton & Stansted) so decided to meet @ Victoria. I know I'll come to the coach station, not sure whether she's getting there by train or coach, but the coach/train station is same place, right...
Ours go out from 6.30ish to about 6pm if they're ridden, otherwise around 8pm. They go out in all weathers unless there is a true storm with extreme wind and rain.
Only one horse isn't too keen on being outside, but they're all used to being out. Unfortunately most fields/paddocks are quite muddy..
