I bought tickets online in front of the London Eye, in my mind skipping the ticket boot. Once (almost immediately) received email confirmation with e-ticket, WITH the notification that it must be printed out (who carriers a printer in its backback today?) in order to enter the same @@! queue at the ticket boot to have the e-ticket converted into a access ticket! If I would have been noticed (very clearly, early in the eticket purchase process) I would never have chosen this service. It took my familiy (small children) 2x30 minutes to find an internet cafe (on sunday) to have our e-tickets printed out on paper. I was perplex when I went back to the ticket boot to get my access ticket and the service advisor JUST scanned the bar code on the paper (could also have scanned that in my email) and provided us the ticket. POOR SERVICE, BAD COMMUNICATION! Oh, I forgot to mention that we were in the standard customer waiting queue for almost 2 hours, seeing 'priority' customers taking over, but that is to blame to Coca Cola company, which is exploiting this attraction....
