When the opportunity to visit WOL was made one of the first things I did was to look for a hotel in walking distance. The drive from west London being a fair contribution to CO2 levels.
I chose the Premier Inn because of its proximity to the NEC. As you can see from the photo less than 300m but you cannot walk it, and the drive is around a mile - not far but not suitable for walking..
When will the UKs flagship centre address this, or do they just want the extra £8 from each vehicle... ;)
