I'm guessing there's a lot of people like me that picked dates and bought hopper tickets before the party dates were released. I realized that a party date fell on a day that we planned to start at DL and then hop to CA for the evening. Since CA will close to us at 6:00, I decided to change my park reservations to start in CA and then hop to DL in the evening. So there might be a lot of people that choose to start in CA and then go to DL in the afternoon/evening when the party starts. I'm wondering how parties affect crowds too since I've never been to parks on party days. I'm worried that DL will be more crowded in the evening since anyone who's buying a 1 day ticket will probably pick DL and those with hoppers will only have one park to be at once it hits 6:00. But oh well we'll make the best of it.
