Some of you may remember when this subject got brought up last year. There was a lady who posted that when she made ADRS she would call four times in one day, in order to make four different sets of ADRs for each day. She used a different phone number (house, her cell, her husband's cell, and daughter's cell) and made four sets of ADRs for each day, because they didn't know which park they would be in, on any given day and she wanted her family to have 'dining options'. She said she did this every trip, so they would have somewhere to eat no matter what park they went to that day. She saw absolutely nothing wrong with it, called it being prepared, and her argument was that everyone had the opportunity to do the same thing she was doing. She said she would book four ADRs for each day of their trip with each being under a different phone number and name, so they couldn't be traced as belonging to the same family. I believe she said that if she was asked what resort she was staying at she'd just say they were staying off site. She had been doing this for several years and saw nothing wrong with it. When people called her selfish and rude, she acted like she had no idea why people were upset with her. Her thinking was that she was doing walk ups a favor, because the three ADRs she didn't use would then have a table available for a walk up.
Personally I would have no problem with WDW requiring a CC guarantee for ADRs. Being late is one thing, but a total no show is something else. At the end of the day anyone who didn't show up or called to cancel would be charged a penalty.
I also like the idea that if someone is 15 minutes late they give the ADR away. There may be some legitimate reasons to be late sometimes, but let's face it, most people that are late to an ADR are probably the same people that are ALWAYS late to everything else in their lives. I have a D-I-L I love dearly, but she drives us all crazy, because she can't get anywhere (and I mean anywhere) on time. She is late for everything in her life. A couple of years ago I took her and my son to WDW and warned her repeatedly before we left that we had to be at certain restaurants at certain times and if they weren't there, the rest of us would not wait even one minute. They missed four ADRS out of seven and the other three my son was literally dragging her as they ran up. We kept our word and ate without them. If they had been totally on their own I guarantee you they would have missed every single ADR, for no other reason than my D-I-L is ALWAYS late. And before anyone calls us mean for not waiting for them, let me tell you I made them a separate, laminated, typed list of all our ADRs and purposely wrote the times as 15 minutes earlier than they actually were in an effort to get her there on time.
