Which one should I go to ?

Bri
On the other one I don't know how to erase it but I forgot to put party.
( Schlitterbahn is a water park )
The water park is with my step dads family. The second one is with my real dad's family. I don't know what to do. 😔 I told both I was going to them. But I had for got about the graduation when they told me about the water park.
