We had planned to stay at Black Horse Farm CAMC site for our Eurotunnel jaunt In 2020. Never happened so can’t comment much more; something about a pandemic.

The black horse farm is fine, used it loads of time for the ferry, but there is a closer CL which is also very good. I forget the name and I am no longer a member. But try searching the CL’s.
Black Horse Farm has a special area for late arrivals and facilities to get in late s is probably the best option for members. Works well for Dover as well.
