Overnight stays near Box Hill
The OYO listing for the Sunday Box Hill Burford Bridge Hotel states that Box Hill & Westhumble station is a 4 minute walk from the hotel, with Dorking station around 1.1 miles away. This is a nearby destination rather than a Leatherhead facility, and the listing does not establish any pickup point, parking permission or affiliation with SDVH. If your group is arriving by train before travelling on together, a minibus can be arranged for the onward journey once everyone has an agreed collection address.
Weddings and events at Horsley Estate
De Vere Horsley Estate markets itself as a wedding venue with a secret chapel, tiled cloisters and a lakeside 19th century mansion, and its website states the site offers 51 flexible event spaces. That figure describes the venue's own spaces, not the number of guests or the size of the travelling party you would need transport for. The venue's website also describes itself as around 10 minutes from the M25 and 6 minutes from Guildford and Dorking, both with direct trains into London, which may help wedding parties planning transport for guests. A minibus suits groups travelling together to the venue, though you should check the venue's own arrival and parking arrangements before your event.
