Welcome to disABILITIES.
The card you are referring to is called a Guest Assistance Card (we abbreviate it as GAC) and I'm afraid you have misunderstood or been given some incorrect information about GACs. The GAC doesn't allow anyone to get on rides without waiting, bypass lines or shorten the wait. They are used for things like allowing a child with special needs to stay in a stroller for waiting in lines, allow a child with autism spectrim disorders to wait in a more appropriate (ie, less busy or less intense) place, etc.
What would help you a lot is to use FASTPASS. With Fastpass, you put your park passes into the fastpass machine and a little card comes out that gives you a time to return to go on the ride/attraction. That is your fastpass. When you return, you wait in the Fastpass return line and your wait will generally be 10 minutes or less. Fastpass is available to anyone with a park ticket and many attraction have fastpass. Using Fastpass would allow you to limit your wait in line and know when you would be getting on.
If you are going during a slow time at the parks (like pretty much anytime from now until Spring break in March -except for around President's Day), you will probably encounter very short waits evven without fastpass. Also, if you need to leave a line, most of the lines are wide enough that you would have no trouble turning around and getting out of line, or if you see a CM, you can ask for an easy way out of line.
I'm sure some of the people on the DIS board with disabetes will have some hints, but here are some other things to think about:
- always have something for her to eat with you in a pocket, purse or backpack.
- if you are concerned about how long the wait in a line is, ask a CM for an approximate wait time before you get into the line.
- the rides at MK are generally short, but some shows and some rides at other parks are longer, with no way to leave once you are on. The Guidebook for Guests with Disabilities that are available at Guest Services used to list the length of rides/attractions. I noticed the updated guidebooks available on line don't have that information, so I'm not sure what the printed versions now have. In general though, you can ask the CM before going in and they will know.
- if you see a ride with a long line, coming back later in the day will usually find a shorter line. A lot of people get in line at the first ride they come to. If you go farther into the park, you can often find things with a very short wait even if the first thing ou came to had a 1 hour wait.
- if you can get to the parks when they open, you can generally get on a lot of things quickly with short waits. Even during july (quite busy) and Spring break, it's very possible to get on 8 or 10 rides before 10:30 am if you can get to the parks when they open.
