I'm intending to go to Kew Gardens on a weekday and it won't be during the school holidays and I wondered if anybody could advise me on the parking situation there? I'm travelling quite a distance but don't know whether to use their car park (have heard it's expensive) or whether I'll be able to park on the local roads. I've also considered parking at a station that is on the same train line as Kew station and travelling in that way. Any advise on that would be appreciated too!!
