Yes, you will get Magic Bands. In fact, your customization window should already be open.
First you need to make sure that everyone is properly listed on your reservation. Next, you will need your 12-digit resort confirmation number. Hover your mouse over My Disney Experience on the main WDW page and choose My Reservations from the drop down menu. The first section is Resort Reservations. Click the tab to link a reservation and enter your confirmation number. It should link to your MDEx account.
Next, click on My Disney Experience. On the right side of the page that loads you should see several links. One should say Personalize Magic Bands. Click on it and you should be able to customize your bands.
If the link says Manage Magic Bands then it has not gone live for you. Some have reported having to do on line check in to get the link to change. If you have already done on line check in and the link does not say Personalize you should try modifying your check in. You don't need to change anything, just go in, click through the screens and hit submit.
Good luck! And have a great trip!
