Are you getting this message:
"The reservation(s) you were trying to retrieve cannot be found. Please check that the information you provided is correct."
I was, and I was stumped, because I could bring up both room ressie confirmations using my home phone number online in the general site, but could get nowhere on the ADR site.
I ended up calling to make (some) ADRs after 7am. 2 calls, also asked both CMs if I was entering the correct info. (in retrospect I realize they both sidestepped the questions..Dissers seem to have more info than some CMs.. not a huge criticism, just fact).
All earlier CMs had asked for my phone number, as if for confirmation of their info.
This afternoon I tried again, and it just did not make sense that some people could access and others could not.
So I called back to Disney, and told the agent I'd like to speak to someone who could help me with the system, was told there really wasn't anyone (Eek! I thought not, but was surprised to hear it, but, it is early days yet, I realize that for all). So, I asked for a supervisor.How much more does a supervisor know than a regular CM, I don't know, but the super I spoke to saw the problem in less than 30seconds. And fixed it. And told me to try before I hung up. (She told me my phone number didn't appear on the reservation! And she entered it in the necessary area(s))
And I'm in!
SO:
If entering your Disney issued/nonDVC resort ressie # & your phone # (eg7095550000) does NOT retrieve your reservation, then call WDW and ask the agent to check thru your rm/pkg reservation(s) to be sure your correct number is listed everywhere a phone number might be.
Before you hang up from the CM, make sure it works in the ADR system.
If it doesn't, politely ask for a supervisor.
I did, and she fixed the issue!
And, because I'm now able to check in the system, I've got CRT and LeCellier for my time & date of choice (not 1st choice, but 2nd choice date and that's good enough for me!)
