My experience is that I had a full 4 days of tests of all kinds initially. I stayed in a hotel. I recommend the old hotel across from Gonda. The Grand Kahler, but only if your room is $100 a night. The walking across the street, subway, makes it worthwhile
Book it once you have your patient guide. Rates go up as the dates approach.
I go back annually now, for just a day, 1 or 2 appointment s.
