To most enthusiasts who would attend such a function - cars, talking and drinking would be the main interests. Travelling ones nearest venue may be many miles and overnight accommodation would be sensible. The geographical location of any venue is a factor but perhaps more importantly a function room or rooms, licensed bar, accommodation and reasonable prices/service ought to be considered first. Any location that is capable of offering this for a large group of people would require pre-booking.
The proposed Founders Night is off-season and an abundance of venues that meet the above criteria are seaside hotels. I suggest that a group pre booking could negotiate some very reasonable terms.
The above is just food for thought but it would be a shame for any one to try and wait another 100 years because enthusiasts didn't communicate.
