My understanding is that they are all licenced by Disney to provide packages.
On another note: has anyone used Magical Enchanted Vacations? I am looking at a W&D registrations and I have emailed them. I know they were at Tink over the weekend, but I haven't heard back from them since. I am getting a bit worried about stuff getting booked out! If I don't hear from them in the next 24 hours I am going elsewhere even though she was lovely on the phone and they were the best value for what I wanted.
