I wonder if the PP that discussed the "selfish" guests that book more tables than they could possibly use and then cancelling last minute wasn't referring to people with a 6 ADRs for 10 days and just switching them around or cancelling ones that they changed their minds on. Rather, the guests that say "I want to eat at BOG but don't know when I want to so I'm going to book one for each day, or multiples in one day" knowing that they're only going to go one time and cancel the rest. If you are going to eat at BOG 7 times, by all means, make the ADRs, but if you are positive you are only dining once, but book 7 that's different. I've noticed the ADR system has fixed this a little bit by having that window between ADR times that you can't book. Doesn't change the 7 ADRs in 7 days, but does stop the 5, 6, and 7 pm reservations all at the same time.
As for CRT, I get annoyed with the "elitist" attitude that some have regarding Disney (not saying OP is in this group but it has been brought up). "I'm staying Deluxe...I deserve more than you lowly Value guests." I hope Disney continues to stay away from this tiered suggestion. Deluxe guests do get more than value guests, the ammenities, dining and transportation options are better. That's where it should end. I love that when you walk through those gates, everyone is considered equal. If you want to dine at CRT, do what everyone else does and wake with the roosters and anxiously stare at a computer screen until 6 a.m eastern time and click away. Honestly, I had zero issues getting both CRT and BOG (in fact, a glitch in the ADR system had me with 4 different ADRs at BOG for lunch, all at the same time...which I cancelled immediately once I noticed it in
MDE).
OP, like others have said, I'm positive you'll snag a CRT ADR. Especially if you are flexible, which it sounds like you are. I hope you and your family have a wonderful time and that your friend enjoys this trip with her girls. 6 is a GREAT age for little girls in Disney.
This is my first trip using FP+ but I was able to book every single FP around my ADRs so I'm a little confused as to how FP+ times would be the reason for people not knowing which ADRs to book. I looked for FP times that were far away in time from any of my ADRs and modified them all to within 10 minutes of when I wanted to use them. I hope I'm not missing something with the whole FP+ thing
