I don't have time to play and chat here today. But I did see that and was afraid there would be 11 pages on it if I didn't comment first.
I have no idea if this is true or not. Hell, I am not even sure if Bob is a grandfather. I just did a brief check (because I had never heard that) and was unable to locate anything that proves he is. He does have two adult daughters, one who is married. Of course, he could have been with his sons and people assumed they were grandchildren.
I have no idea whether or not Micechat actually checks the validity of 'reader mail' or not.
But I can safely say that whether this was true or not, I don't believe the timing was coincidental. Bob knew Michael was going to WDW and who he was going with before Michael tweeted those adorable pics to the world. He also knew that people would make the usual excuses they do for people of power and privilege getting to cut in front of the rest of the dirty huddled masses. So, very few people would be angry that Bob Iger doesn't wait for anything and simply goes in front of people who paid to be there.
I do find it amusing that this little note just slid on into that column after the EisnerTweets, though.
Y'all have great Fridays ... and weekends!
