I went on Tuesday so thought it might be worth sharing my views. I felt there was a rather a lot of pointless advertisement. We didn't do the 4D part but the queue line security strap (I guess that's what it is called :S) was covered in Coca Cola wording, then the inside like people have said above has some advertisement. I took a photo to show part of the inside:
Each pod also had coca cola written on it that could be seen from the outside. We didn't see it at night so I can't comment on the lighting.
As for the experience has anyone been on it recently? We thought it was a forty minute ride but we timed our time in the pod and it lasted just over 20 minutes. We were actually quite disappointed with the whole experience.
