I am making this after having spoke to guest experience team in DHS today.
The woman told me that groups are filled in order, meaning they are NOT random (1st person gets first boarding group). Now, you may tap it before someone but have a slower device than those who hit it 5 seconds after you, or the server may register requests oddly because of the max influx of user requests.
Based on this, it is not worth (what I previously theorized) getting passes for your group, but not for you, and refreshing boarding groups only for yourself to see if you can get a lower number and get your family moved to your group.
This strategy is one I think is very much worth attempting when you can:
1) Be in the park before 7AM with a party of 2 or more. Ensure before 7AM that all of you have the WDW experience app and have your entire party linked to each person’s account/phone/app (as if you need to select fast passes for them).
2) Have the app closed and leave it closed until 7AM before you enter the park. It needs to register that you’ve tapped your magic band. (As a side note - the ONLY requirement to obtain a boarding pass is that you have tapped your magic band or pass to the tap station at DHS and that it turns green. You can make a 180 degree turn and walk right out if you wanted to, which is actually strategic for rope dropping another park. Just get to your phone at 7AM wherever you are).
3) Split your group into 2-3, depending on what you want to do or feel comfortable doing. You will need to speak to a cast member and get them to move your party to the group you want (that you’ve chosen).
4) At 7AM, open the app and join a boarding group. I like waiting 2-3 seconds to open the app on good connection. Have each person do this. Do not overlap people. I will give an example here for a group of 3:
Person A: obtains a pass for person A and B.
Person C: obtains a pass for person C only.
This can extend to however many people you’d like. Just know that the more divisions in groups, the harder it will be to get a CM to shift all of you around.
5) Because 2 people are trying, theoretically, you have twice the probability of getting to a good boarding group if you each do it ASAP at 7AM. The more people, the higher likelihood you are in a low group, but also the harder it is to combine groups with a CM.
6) Go to guest experience umbrellas in DHS with your party. Personally, I’d recommend referring to your party as “family” to ensure CMs help you out more. If you don’t like bending the truth a little, simply don’t use this strategy. It will probably work - combining someone to your more favorable group - but if you aren’t comfortable doing this, don’t.
From here, hopefully, you have obtained the lowest group possible that your party has found with several people checking the app at the same time and sending those requests to Disney’s servers.
Let me know what you think and if you test it!
