Just figured I'd add my 180+ ADR/AR experiences to this thread; I think they are relevant. May main tip to anyone out there is to not get frustrated, and to keep trying.
On 05/22/2018 I logged in at 5:58 AM for online reservations; I called in at 7:00 AM for call in reservations (BBB & Wonderland Tea Party).
We are planning a multi-family trip to WDW the week of Thanksgiving. My intended reservations (in order of importance) were as follows:
1 - 11/20 Bibbidi Bobbidi Boutiqe for 2 DD (call in) - Called in right at 7AM Central, and was able to get an afternoon time without issue; being flexible helped.
2 - 11/20 Cinderellla's Royal Table (wanted a time a bit after BBB) - Logged on at 5:58AM and was unavailable; did not get this reservation at 180 days.
3 - 11/22 Whispering Canyone Cafe (17 guest reservation) - Tried this one after CRT, and was able to get lunch time (when we do Thanksgiving); had to split into two parties of 9 and 8 due to size but was accepted.
4 - 11/21 Wonderland Tea Party (3 guests) - Requested this after getting the BBB reservation, and there was none available for this day or any days around it.
5 - 11/21 Yak & Yeti - This was my 3rd online reservation at 180+ days, and was able to get a dinner reservation for 4 without issue.
6 - 11/19 Garden Grill - This was my 4th online reservation at 180+ days, and was able to get a dinner reservation for 4 without issue.
7 - 11/26 Ohana - This was my 5th online rservationa at 180+ days, was not able to get the reservation due to this being 2nd half of our split stay.
The second half of our split stay 180+ days opened on 05/27/2018. I actually forgot about it, and didn't get online that day till about 5PM. I was able to reserve the 11/26 Ohana at 4PM for a party of 10 (not split) without any issues.
The only ADR I was missing, that I really wanted was something for after Bibbidi Bobbidi Boutique on 11/20. I wanted to try for Cinderella's Royal Table or 1900 Park Fare on the same day around early dinner time. I have a touringplans membership so I used their ADR search tool for both of those restaurants.
On 06/01/2018 I received a text from the touring plans ADR search tool for an opening at 1900 Park Fare. I clicked to get the reservations, but then decided to log onto
MDE and see what else might be available.
I found two times for Cinderella's Royal Table and two times for 1900 Park Fare that were available. I reserved the Cinderella's Royal Table.
I am only missing the Wonderland Tea Party (no biggie), and will probably try calling in every so often to check on that one.
Most interesting part of this whole ordeal was that a highly sought after reservation (CRT) opened up almost a week after the 180+ day mark. This is the main reason I say not to get frustrated, and to keep checking/trying.
Just my experience, and my humble opinion.
