Support a Heartfelt Reunion for Graduation

Some years ago I was separated from my twin daughters due to circumstances out of my control. Now, they are 18 and I'm trying to surprise them by attending their high school graduation. Yes, I was invited. Unfortunately, I have come up short for a rental car and hotel. This will be the first time they meet their little brother as well. I just want to give them the reunion they have been asking for. This is what they want for graduation and it has been breaking my heart that, at this moment, I'm not able to make it happen.
