Putting in a new big E-Ticket isn't going to solve crowding problems, in fact, it could make them worse. That's what we're all expecting when SWL opens. It won't be a case of: "Whew, DHS is so much less crowded because the new lands are 'eating' guests!" It will be a packed nightmare instead.
When you have any-time ticketing strategy where you sell more tickets than the parks can handle, then there will always be crowding issues. The better solution is spread crowds more evenly by:
- Discouraging peak attendance and encouraging off-peak attendance (done usually with resort deals in the off-season; and surge pricing and AP blackouts)
- Move crowds to less dense areas: Make the three parks that are not the MK as desirable as the MK.
- Make attractions that are currently less attended more attractive by upgrading them or even replacing them if you have to.
OR, you move to a system where tickets are only good for a specific day and they limit how many tickets they sell for that day. E.g., the Christmas and Halloween parties will never have a "phased closing" because too many people show up. The number of tickets sell out, and no more tickets are sold and no one else can get in. That's a nuclear option for dealing with the overcrowding at MK, but, it's a solution. Other than that, all you have is carrots (to move them to less dense parks/attractions) or sticks (increased pricing).
OR, you make sure your parks' capacity greatly exceeds the capacity of all the local resorts, hotels, and local housing. Then, rooming will limit the crowds.
