There are two big questions: 1. What do you want to do? 2. What will bring you closer to your goal?
If you really want to go to Disney, tell him that you will go with the kids and he can join you if he wants. And leave it open to him to look for his own hotel room and car if he wants. You get your stuff ready for the kids and you. Just do not press the issue too hard. Manesha is absolutely on target in her post.
On the other hand, he might want to go himself and leave you behind. He may use a trip to Disney with the kids as an opportunity to let off steam and think about himself.
My H and I found that separate vacations with our D helped: I went in May and learned to confront myself and my past, and he went in August and decided to return home. They called me once a day and I did not find that week lonely at all but an opportunity to be alone with myself and my thoughts without pressures.
If you are concerned about money, bring up the subject. Are the tickets refundable?
