Update

After a few setbacks with Ethan's surgery dates, changing our airline tickets, trying to find a place to stay while there, etc., we are finally set.
Collette at the Quantum House was able to work with us and give us a place to stay, which was a very big relief for us since they are across the street from the hospital.
So we fly in on May 17th, 18th will be pre-op and MRI, 19th is surgery day.

Side note: for people trying to schedule a surgery with Dr. Paley, you have to be flexible and strong. His assistant, Sarah, makes many mistakes and it cost us plenty of money to move our travel plans. So just be weary and try to stay on top of your dates or she will change them.
