Steve,
Yes, the waiting game is frustrating regardless of what you're waiting for. I disagree however, that it isn't worth the wait.
Only you can make this decision. Dr. Regan has an excellent surgical reputation as does Dr. Bitan. I believe either one will do as good a job as the other. If you don't have a personal preference and can save $5000 plus hotel costs in Los Angeles, then yes, wait a few days more. Dr R's office staff may be waiting for confirmation from hospital, other doctors or whatever. Dr. Bitan may just know that everyone will come on board if necessary. You might want to call Dr. Bitan's office to explain your situation and see if they can't do better.
Personally, I was born and raised in Brooklyn and now live in L.A. If I had to travel,
This isn't exactly a heads or tails decision. All things are not equal.
Hang in there, Dale
