Allow an hour from the M6, and aim to be in by 9 at the very latest, earlier if you can, to get George settled (and you!). The queues into the car carks can be horrendous.
Definitely use the West Car Park, its nearest by far to the buildings. Follow the signs off the motorway for Birmingham International Airport, and the British Rail signs (the two red and white 'arrows'). This will take you right to the roundabout where the station is, but instead of going into the station entrance follow the signs for the NEC West Car Park. When you have parked you only then have to walk across the car park (huge) and under an underpass below the railway line, across the perimeter road and you are at the buildings. If you have not got a car park pass you can get them from the booth either on the way in or out,
and if you have not got a separate pass for Mr Thug just follow someone in with several dogs and bags, and offer to carry a bag, as they will have a pass for each dog to save you paying.
You get your catalogue just inside the doors, and then have to find the hall/ring you are in where your benches will be. Don't forget to keep your removal pass handy for on the way out. There are several outside exercise areas that you can use during the day, if he doesn't like the inside sawdust ones. Don't forget you cannot leave until 4pm, but remember also there will be a mad rush to leave and after that the queues start to get out of the car parks! all in all a very stressful day but wouldn't miss it for the world. I will come and find you as we are in the next ring to you, Hall 4 ring 20, but we are the third breed in our ring.
Enjoy!
