Update 10-2-2018....
MANY folks have now encountered the new, partially broken, WDW Website. Another mess, with no Change Control, no testing.
Let's start with the BIG one -
HOW TO LOG IN:
--to get to a log in page, hit "My Magic Bands and Cards", or anything OTHER than "My Disney Experience".
The rest - typical.....
PRINTING RES NUMBERS has gotten nastier... You will need to print TWICE - once for "Daily Itinerary", once for "Tickets & Memory Maker". Main page does NOT "show" you what it says it will... either PLANS, or TICKETS.
"Tickets & Memory Maker" provides NO Confirmation numbers. CALL CALL CALL.
New "Plans and Tickets" has no "print view". When in doubt? PAGE CAPTURE as a series of JPGs.
Once again - MAJOR change, no advance notification, no Change Control
. Unprofessional 
.
Majority of underlying Website (things like "Dining") - unchanged. However -
MANY broken links, giving you Stitch.
PLEASE - if you do not have printed confirmation numbers for everything? GET THEM, for your own protection. CARRY these, on paper, and as a PDF on your Cell Phone?
MDE is an unstable website... anything could change without notice, at any time 
.
All personal opinion - I'm not necessarily right, no one else is necessarily wrong.
