Very good discussion. Excellent points as usual, Bicker! Here are my thoughts:
1. Just because people promise to cancel ADRs, this may not be that much of a help either as several posters didn't specify when they were going to cancel. So, if they cancelled a couple of hours before, they are still tying up an ADR for someone else to use. Sorry, it's the English teacher in me coming out, but not many posters who have 2 ADRs said when they were going to cancel - their 'soon' may not be my 'soon', especially if their trips are days or weeks away! It baffles my mind how unplanners think having multiple ADRs are going to help them - if they can't decide at 180 days out where to eat, what makes them think they are going to be able to decide at 7 or 3 days out? Make 1 ADR and that's it, please!!!
2. I just called yesterday to make a couple of changes to our ADRs for July (that have been booked since 180 days), and before I even said to cancel ones that ended up being on duplicate nights (I switched a few restaurants), the CM was already in the process of cancelling. I guess it depends on what CM you get, but the efficient ones are recognizing that people have multiple ADRs and are calling people on it. The computer system itself though is another story as I was able to make my switches first, and then they were cancelled. The system is set up for this, but perhaps they could red flag multiple ADRs if possible.
3. Growing up in a restaurant family for my entire 35 years, I can tell you that people don't take reservations seriously. They think it's no big deal for restaurants or other patrons to make multiple reservations, not show up, or show up with 5 extra people! I see this at Disney all of the time. People are selfish, plain and simple. If people were altruistic in nature, and thought about how difficult this is for both the restaurant, and other patrons, it wouldn't be so bad. In my experience though, I've learned that most people think of themselves first, especially when dining out in public.
In some cases, multiple ADRs are legitimate - parents splitting up with kids or other members of the party wanting to eat at different restaurants, but, from what we read on the DIS, most of them are to accommodate the unplanners - people who can't decide what park they want to eat in until they get there. I have family and friends who are like this - they think the whole world revolves around them, and so they feel that all restaurants, stores, vacation destinations, etc. should be able to accommodate them at all times! These same people get angry when they want to bring 7 people out to dinner in the next 5 mins. and the restaurant can't accommodate, or they want to take a cruise in 3 days, but there aren't any flights left. It makes my head hurt as I think of everyone else who is sharing Disney with me as being just as important as my family - especially when making dining reservations.
Basically, until Disney implements a credit card policy, or some other flagging/cancellation system, then people are going to continue to make multiple ADRs or use the Dining Plan incorrectly, because as we've also seen many times on the DIS, some people are very insular and selfish in regards to how they conduct themselves in the world. For us, we plan our days around our ADRs, and that's the way it needs to be as we are vying for the same dining spots as 40,000 other people on a daily basis. It's too bad some people feel they don't have to follow the same logical planning as the rest of us!
Happy eating to all, Tiger
