I think you are a very generous and kind person to be gracious enough to make room for her in your vacation. Your daughter is a VERY lucky girl, and I know that these memories will not be forgotten. She will always know that you made room for her mother - and that will just help to enforce her love and respect for you.
That said, I would not make ADRs with your ex. I also worry about the chance of her expecting you to foot the bill. Let her share park time, and counter service with you. These will mean as much to your DD as a fancier sit down meal.
Very honestly, this is about what is best for your daughter - not you or her mom. I think you are taking the very best of the middle roads. Bravo to you!




One thing to keep in mind is that your ex-wife might not end up coming. I know that my ex-husband (who is a deadbeat similar to your ex) called and wanted to take my son to his hockey game but he didn't want me to be there - he wanted to do just the 2 of them. I said Okay because I knew it would mean the world to my son to have his dad at one of his hockey games - well, the morning of the hockey game, my ex called and couldn't make it after all. My son was obviously disappointed because at age 5, he realizes that he is the only kid at hockey whose dad has not shown up.

Your ex-wife might pull a similar thing with the Disney trip and back out at the last minute so I would not change any plans for her. If she shows up and wants to play "mommy" - let it happen for your daughter's sake but don't structure your vacation around the fact that she is "planning" on joining you. And really, she doesn't need to join you for all the meals - she is an adult and can take care of herself for a couple of hours. JMHO.
Good luck and I hope you have a wonderful time at Disney!
