We are staying at AKV Jambo House from Oct. 5-7 and BLT Oct. 7-10. After I did the online check-in, I was able to do FP+ reservations. First only online, but not in the app, but after a few days it was also working in the app.
However, when I clicked the link for the Magic Bands, it just gave me a page with basic informations about the Magic Bands and saying "Coming Soon" at the bottom.
Then, about 2 days ago, when I was playing around a bit in the MDE app I was ask to confirm my shipping address and then could choose colors and names for our Magic Bands.
While it says in the FAQ that bands are not shipped outside the US, I was able to enter my address in Switzerland. Though there is also a info popup that says if the address is outside the US, the personalized bands would be available for pickup at the hotel when checking in.
What I found strange though is that in the FAQ it says that the customization deadline is 5 days before arrival, the deadline for me is shown to be exactly 1 month before arrival (Sept. 4, 2013), which makes me think that at one time they probably were planning on sending the bands to international visitors as well, extending the deadline for non-US addresses to allow enough time for shipping and when they decided against it, someone forgot to tell the IT guys...
Another IT hiccup I noticed is a partially used Non-expiring park hopper which I have assigned to my account which shows an expiration date of Dec. 31, 2030.
