Hi Lewis,
I was trying to make Advance Dining Reservations (ADRs) for a friend just a couple of days ago at 180 days out and although she had obtained her 12 digit US Resort confirmation number and was able to retrieve her package/room reservation on the USA version of the Walt Disney World website, for some reason, I was not able to get this to link to the Dining Reservations page.
In this instance, I would recommend that you call and speak to a Cast Member on 001-407-939-3463 who will be happy to make dining reservations for the first 10 days of your holiday. Lines open at 7am EST which is currently 12noon here in the UK. (In order to make an economical telephone call from the UK, you can
either use Skype or call 08448-610-610 and when prompted enter the US
telephone number which in this case is 407-939-3463. Calls will cost
approximately 1p per minute which is obviously much cheaper than making a
normal international call)
To help you with your planning further, why not visit the
My Holiday Planner
website where you can watch a number of videos including my top tips
which are aimed specifically at helping UK Guests plan their trips to
Walt Disney World.
You will also be able to order a copy of the Little Big Book of Magic
guidebook which contains pull out maps and insider tips to help you get
the most from your trip as well as a Walt Disney Travel Company brochure
and some other planning tools.
Wishing you a magical holiday filled with memories which will last a lifetime!
