We did the dessert party a few days ago in between two party days, and were glad we did. The hub and a good chunk of Main Street were packed to capacity. About 30 minutes (maybe more) before the show, groups of three CMs on either side of the hub ( both front and back 'parts') were 'blocking' it off to additional people, and were directing people to use the walkways behind the shops that are normally closed to keep traffic flowing before the show. People would go down the back way then come back up Main Street as far as they could. They were not directing people to move forward- but were, as mentioned, directing people away from the hub to the far end of Main Street then back up. There were also additional CMs behind the garden area in the walkways preventing people from hovering there- and directing them towards the back walkways. A few people ‘snuck’ through, but there is no way that anyone was going to show up 5-10 min before the fireworks on the evening we were there and get a good spot in the opposite garden in front of Casey's- they wouldn’t even have been able to get anywhere near that area with all of the CM’s directing people away. I wouldn't say it was impossible- as with a lot of pushing and shoving a person 'might' have been able to wedge themselves through the throng of people to get there- and then someone 'might' magically yield their spot to the person- but it seems improbable to me- just my opinion. So...realistically...if your son really wants to see the fireworks from a good viewpoint in front of the castle area- tell him to get to the hub area at least 60 minutes beforehand. If the crowds were like what we saw and is typical of a non-party day this year, 60 minutes is pushing the outside limits of what I can, in good conscience, recommend as a MINIMUM amount of time to arrive.
