Usually don't stay onsite but doing so in Oct. I see people saying they were picking their bands and stuff before they shipped but I don't know how to do that. Any help would be appreciated.
You sign into your "my Disney experience" and you can customize your bands. I find doing in it from a computer is sometimes easier than from the mobile app
Customization includes picking a color and naming your band/s
First you go to https://disneyworld.disney.go.com/plan/ and log in. Then you go to customize magic bands. Need help? Come back here!
I hope you found the link on MDE! What color(s) did you choose? You can choose names that are different than your real names if you want. The names are printed on the inside of the bands. That way you can tell them apart even if 2 are the same color.
