Gerri, the e-ticket process is easy and fast! You just go to the DLR website, pay for the Hopper with your credit or debit card, then DLR sends you an email with a PDF of your e-ticket, which you then print out (and you can print out extra copies for back-up, just in case) and take to the turnstiles at DLR. The CM at the turnstile scans the paper e-ticket and gives you a 'real' ticket in exchange (which you can use for Fast Passes, etc.). It takes about 5 seconds! You never have to deal with the lines at the ticket booths!
