First I want to preface any complaining I do here with, I am so grateful for the DAS system. My husband is fairly ill, and it made the difference in our ability to stay in the parks a decent amount of time vs a 2-3 hour day max.
Also, take all of this with a grain of salt, because we went this year 2 days after they initiated Genie. Oct 21-27.
I thought you had to use the preregistration system to be able to have a DAS pass.
So, I tried I believe one day for 3 hours and the next logged on at 7 am, and was finally connected with the CM we had to speak to at about 8 pm.
She spent a fair amount of time setting us up, but somehow left my son off of our group. I called the next day when I found the error (the day before our trip) and the GS CM told me the program was such a hot mess it had been temporarily taken down from the website and she recommended we try to fix it on our first day there.
As it turns out, each day in the park I had to go to either GS or a GS group under the umbrellas because no one could successfully get him added on.
The complicating feature was the preride registration. It sounds good in theory but I'm not sure of the purpose because they give you a time whether it works or not. And the system on MDE made it very difficult to cancel those scheduled and therefore you couldn't try to book something else without GS assistance.
If you don't mind the time on your first day going to GS, I personally in retrospect would have done that.
And, these bugs may have all been worked out by now, I am not sure.
If you have any questions please feel free to DM me.
