DO NOT BUY DISNEYLAND PARIS TICKETS FROM VIATOR! I bought tickets to Disneyland Paris. We arrived one hour early to ensure front-of-line access when the gates opened. We were denied entry at the turnstiles with our Viator tickets and spent one hour after the gates opened resolving the issue at the Disneyland ticket booth. We ended up buying a new set of tickets directly from Disneyland Paris and were told this was a COMMON PROBLEM WITH VIATOR TICKETS! As a result of missing the "golden hour," we ended up spending an additional $500 on Disney Premier (aka Fast Pass) to make up for the loss of time and opportunity. DO NOT BUY DISNEYLAND PARIS TICKETS FROM VIATOR!
