If you currently do not require the use of adult incontinence products (or "diapers") then you may indeed find them difficult to use with intent. Most people who ordinarily have control of their bowels and/or bladder would find it quite discomforting to try and use an incontinence product intentionally, especially in a public, exposed situation.
If you have concerns related to waiting in line (for example, you have a physical issue that requires you to be able to wait outside the line, like incontinence or frequent urination) that you can request a
DAS at Guest Relations in any of the four Parks at Walt Disney World (Magic Kingdom, EPCOT, Hollywood Studios, and/or Animal Kingdom) Guest Relations is inside the Park (requiring a ticket to enter and speak with Guest Relations) Some people have reported being able to get their DAS prior to entering the Park, either at Guest Relations outside the Parks, or during a recent trial, at the Ticket & Transportation Center.
To be able to use the DAS, you will need to tell the Cast Member at Guest Relations *why* you can't wait in the line with the other Guests. It is important to note that they will not accept a doctors note/letter. They will not issue a DAS based on diagnosis, but instead will discuss only why you need the accommodation of waiting outside the traditional queue.
Regarding the wheelchair, regardless of where you are staying, it is recommended to rent one for the duration of your visit, as there is often a great deal of walking outside of the theme parks as well (thinking now of large hotel Resort complexes, Disney Springs, etc.) Do not rent a wheelchair unless you have someone to push you, or unless you use a wheelchair daily in your "everyday" life at home; the average Guest will travel between 3 & 10 miles per *day* at Disney World, and the average new wheelchair user will not make it from the Train Station to the Castle Forecourt at Magic Kingdom without their arms turning to noodles, and their shoulders giving up.
