So if I were to going during Easter, I'd stay onsite, I'd be at the gate a half hour before EMH begins and I would get a tonne done in the morning. Then I'd take a break when all the lazy people show up and relax and let them slug it out. I'd then return in the evening to enjoy the shows and just put up with the crowds at that part of the day. But I have yet to have to go during that time but I am sure one day we will.
The problem with spring break this year is there is a large portion of DL that is offline for over a full year. Normally by the time spring break comes they make every effort to have most of the attractions up and running so as to absorb as many people as possible. So I think this year, with the ROA and the railroad down, it will be even more crowded. But only time will tell.
If you are a patient person, who does not need a lot of personal space and you can get up early and make use of your morning hours then you will likely have a great time. If you won't get there until 11 each day and hate it when people are in your space, you might end up being a little crazy before you leave.
