I have had the unfortunate experience of being a Comcast customer once. Comcast's customer service is one of the worst if not THE worst I have ever dealt with. Our family switched to Direct TV to be rid of the Comcast monopoly in our area. We even reconsider going to events that are sponsored by Comcast.
One thing that has always drawn us to Disney is their customer service. I have owned my own business for many years, and it's nice to go on vacation where you don't have to worry about anything. This is why we bought into the DVC in 2000, and have made the investment and committment to vacation at Disney for the next 38 years.
If, God forbid, this merger goes through with Comcast to include the theme parks and DVC, we will sell our points. We won't wait around for the inevitable degradation of Disney's customer service thus the drop in resale prices.
If any deal is to be done with Disney and Comcast, how about just the media parts - ABC, ESPN, etc? Leave the theme parks, hotels, DVC, etc alone as a separate entertainment and tourism entity.
