Ok I am all caught up, whew! I am so depressed

My bil & his family are going to Disney in April. Their dd(my niece) is going to be in the parade with her school band. I would love to be able to go & see her. Then last night I found out my db & his family are going at the same time. Most of my family will be there except me, no fair
I always thought it would be cool if we could all go around the same time, well it's happening but not with me. So I am having a pity party for myself

I told dh most of our family will be there at the same time & his reply was, but we won't

I wish I could figure out a way to go
