Indigochild - hoosiergirl went on her own and loved it (sorry to speak for your hoosiergirl) and her blog and comments gave me great comfort before I went...that said, I didn't go alone, but there are many there that are unaccompanied. Once you're there - you're not alone - you will meet many people at the hotel, all in the same boat, just not all going to the OCC. Don't be shy about going up to chat with folks - granted not all big people are there for surgery, but really, the vast majority are. Look around the lobby, around the pool and in the restaurant, you wont be short of finding a "sleeve-family" member. Also, contact the OCC and ask if you can intact any others scheduled for the same day. Sometimes you can get their email address and establish contact. My sleeve-sister at the OCC on the same day has become a new good friend - the positives from our decision to be sleeved and take back our lives are many and some unexpected. Good luck to you, you are in good hands.
p.s. Batman and Robin also have Wonderwoman (Dr Victoria) - who was the doctor on call post-surgery all night. She's gorgeous inside & out.
