We usually get around 20 members coming over the entire weekend and we just chill out and hang out together.
On the Saturday and Sunday, we will meet 1pm onwards on the Upper deck (open air), of a boat called the Tattershall Castle, which is moored on the river Thames around 100 yards from Embankment Underground (Metro) station:-

We will leave the boat at 6pm and in the evening, we will sit on the grassy areas on the South Bank of the river Thames beside the London Eye and listen to the live music and watch the firework display over the Thames. There are food stalls all around and we can sit on the grass and eat/drink.
The meetup is a means of networking with other sufferers, exchanging tips and having a nice time. Believe me, you will learn more from other members than from any doctor or scientist. As a Group, our members are our specialists! They have a variety of experience.
Members usually can not smell one another (since we produce similar chemicals in our odour) so don't worry about other members smelling you, they generally can not!
Some members coming from far will be staying at Travelodge London Tower Bridge Hotel and the address is:-
Lloyds Court Business Centre
1 Goodmans Yard
London
E1 8AT
Tel: 0871 984 6388
Fax: 0207 6809166
This hotel is 200 metres/yards from Tower Hill tube station and you can conveniently get the District Line train to Embankment tube station where The Tattershall Castle boat is moored. However, there are lots of good deals on other London Hotels on Hotels.com and other sites if you book now.
At the festival I will have my mobile phone with me all day and the number is 07753 492 759 and it is often better to text me (especially in the evening) since the music can sometimes be loud. I will check for texts every few minutes.
