Well, we may not be "real life," but there certainly are plenty of Disney fanatics around here! Welcome to the club!
You mean "the
original Disney"?
All these hotels are favorites on this forum. The CCI is one of my two regular hotels at DLR. You can't really go wrong with any of these choices. And being walking distance, especially with the short time that you have, can make a difference.
Give yourself as much time as you can. Personally, I would aim to be at the gates earlier. A 9am opening is late for DL, so there will be more crowds at the gates. The more time you give yourself, the bigger advantage you'll have, especially if you get hung up at bag check. I assume your hotel shuttle will drop you off at the Harbor shuttle stop? If so, the Harbor side bag check can really back up at certain times of day, so allow more time to get through. If you get to the gates and you feel you are way too early, then head for DTD to shop or get yourself a treat. Then go back to the gates.
