Thank you.

I am really looking forward to both trips. I have 2 teenage DDs and a 6 yo DGD so Universal should have something for all of them. We will be there for my DDs 15th bday and she loves

so we will probably spend that day at IOA.
I feel the same way as you. I know it will be crowded but we will enjoy whatever we can.
And yes, if you are staying at a Disney owned resort you can make ADRs 90+10.
Have a fantastic vacation!
