Congratulations on your upcoming wedding, we hope that everything goes well for you!
A VW campervan as a wedding car is a super idea, but as you say not the normal rental for such an occasion
We have a previous community forum post on Wedding information
with an answer by a fellow member Ciaran, that may be of interest to you.
There is a VW Camper company called Retro Camper Ltd
, that does indeed offer a wedding rental service. Please do get in touch with them and see if they can offer you something that fits in with your plans.
I'm sure our Industry partners and fellow members will have some advice also.
We hope this helps get you started,
