Thanks. That's what I surmised.Only done it once, but it was straightforward. Just click on the items you want to purchase. I do nog think I got an email. If you pull up the reservation in MDE, you should see the date you can place your order. I believe you can at approximately 30 days out, but there it is not a huge rush. You could probably place your order right before you got there and still be ok.
On MDE app, go to : See my plans; scroll to your BOG reservation; click on it; scroll down to Place or Modify OrderI can't see the preorder on the app. I have to go to the website. Just an FYI. I kept looking for it on my app and wondering why I couldn't see it.
