Hi Pam, I did not need a flashlight. I have a flashlight on my iphone, but did not use it. I had the second timeslot at 4:20 so it was not completely dark when I arrived. It’s a straight shot from the tube station to Kew gardens. I believe there was a sign, but it’s the main road in front of the station that takes you past the homes mentioned above by Jean and right to the Kew entrance.
The path through the garden was well lite. I never had a moment of wait, I can’t see, where do I go. Also, all along the path there were park employees in fluorescent vests ready to help if needed. Plenty of toilets throughout. And various stops for food.
Not knowing what to expect, I was really impressed with the setup. The main giftshop near the entrance stays open late. So, you can stock up on all the bar soap afterwards.
I have a tip that I posted on another forum thread: I let my group at 4:20 go ahead of me and then it pretty much felt like I had the place to myself. But, you can’t linger too long, or the next timeslot group will catch up.
I’m on the mailing list for Kew Gardens, but I did not sign up for the Fever one. Not being familiar with that site, I didn’t sign up. I’ll add it here if others would like to sign up, but I would purchase tickets directly from Kew once they are available.

Also, I found both the visit London

and secret London

Facebook sites to be great resources for finding out when all the lights would be turned out, Christmas markets opening, etc.
