We're staying at the local town for 5 nights with day trips into Paris too. Going to spend 2 days at DLP. Just wondering if we need a 2 day ticket for both parks at the same time or do one park one day and other the next. It's a bit cheaper buying tickets that way on the dates we're going. Prob going to go on the Tues and Weds over May half term as looks a bit quieter then according to French website. Thanks
