Hmm, it's been a heck of a week this week for me so forgive me if I am not awake and missing something (which is VERY possible), but if you are in your 180 day window already, as you will be if you are going in February, you don't need the US reservation number at all. The point of having this is to reserve the first 10 days of ADRs on the first (180th) day.So are you unable to make reservations for dining or are you trying to call up your resort reservation? Sorry, little confused here
Edit to add: If it is just your resort reservation you want to retrieve, they cannot do this by phone on the US line. You have to go through the UK line and use your UK reservation number. As for the ADRs, again, I suggest that you go ahead and book them. You can do this without the number at this late stage. Hope you get all the places you are hoping for!
I can make reservations for dining, however I can't connect them to my disney dining plan, as when I select "use disney dining plan" it asks for my number, surname and date of stay. When I put them in it give me that error message.
I'm not bothered about linking most of them (I've just reserved using my credit card where necessary), HOWEVER I can't book Cinderellas table as that requires full payment with the booking. If I can get it to accept my number I will be able to book online.
I can see my room reservation on the US site, using my 12digit number, it's only the dining part that isn't working.
