My wife and I are planning our London trip in May. When we leave London, we were hoping to catch a Southern Railways train to Gatwick Airport, changing at Clapham Junction. We'll each have a medium-to-large sized suitcase on wheels, plus a backpack each--we're both in pretty decent shape, but wouldn't want to lug everything up multiple flights of stairs at once if possible.
1. Will there be any issues taking that much luggage on what is, if I understand it, essentially a commuter train? Is there any place to park the luggage on the train next to, or near, our seats?
2. How difficult is it to navigate the platform transfer (if any) at Clapham Junction? Bear in mind that I read maps for fun, and am perfectly adept at following signs in railway stations; so as long as everything's clearly laid out, I should be fine...but are there any issues that might make this an undesirable plan to get to Gatwick? I've read some people on TripAdvisor warning people that the Clapham Jct transfer can be dicey.
