For the first time i decided to stay over night as one of the guests i wanted to meet was signing Sun only. We stayed at a hotel about 15 mins from the stadium. Althought we got a taxi there, we got the free bus back to the train station with no problem whatsoever on both Sat and Sun. I didnt see any notices about the free bus to be honest, but i just asked at the organisers booth and they told me cleary where it was. I had a really good weekend and thought it was brilliant meeting all the guests (and i could spread it out rather than rushing about in one day!)
The one thing that was a problem was the crowds. Although this is a good thing (as it shows the popularity of the event) it was a bot of a pain when there was no room to manouvre and people just stood in the way! Maybe it would be a good idea to have a reserved area for 'standard' people to go to so they can meet/relax whilst waiting for the guests rather than blocking off the walkway. I noticed they had a gold pass area, bt i struggled to find somewhere warm i could go to, away from everyone just to get a few mins.
I had a fab weekennd and met everyone i wanted to...which is what it's all about and all of the crew were very helpful and friendly :-)
