I have long been in favour of moving the Notting Hill carnival to Hyde Park, but the scale of the event is completely different. Carnival closes down every street in a large area of West London for 4-5 days and it attracts millions of people to an area of London simply not built for events of this size - that is what Hyde Park and Crystal Palace are for.
Jerk Cook Out still remains a much smaller event than carnival (under 1% of the people that attend carnival). Rather than trying to move it out of Forest Hill we should be finding ways to make it work better and turn it into a Forest Hill event.
As well as addressing parking issues we can pro-actively encourage people to use public transport and to park further from Horniman. For example a steel band outside the station, welcoming people to the area and encouraging people to park in the Perry Vale and Sainsburys car parks, knowing that they will immediately be at the start of the festivities. This would also benefit local businesses by spreading the money coming in from the event across the area. The park was just about at capacity yesterday, by organising some extra attractions across Forest Hill we could reduce the overcrowding by spreading out people better.
