I just think their logic is a bit faulty especially the bit about accidentally going over 10000. They should not be accidentally going over 10000 but if they do by 10-20 people who would be counting? If they think someone would be counting then the Horniman could easily do their own counting by checking people in at the gate. The use of a clicker would tell them how many people are attending these events. They seem to be ignoring the fact that in order to confirm excessive attendance someone needs to be counting them in from the start.
The Horniman need to start to build up a bit more trust in the community that had previously dissipated over the last two years. This just isnt doing it for me. I certainly dont want to see alcohol for sale in the shop which they seem to think is acceptable nor necessarily in the cafe at least during the day. I would imagine that if they want to serve alcohol with meals then the price in general is likely to increase. I remain deeply concerned about their logic and statements they have made. If a licence for 14999 is obtained the Horniman is likely to want to use it. Why can't they apply for a reduced capacity and then seek a temporary licence extension two or three times a year for special events? That would achieve their aim and also go some way to balancing the various interests.
As to where people will park, the answer is your road and mine. The Horniman are still despite public protest advertising available parking on local roads.
