Solar, a little bit of advice. On Choose and Book, you don't get the surgeon of your choice, you get whoever the Appointments clerk choose to allocate you to. The way round it is this: when you get your letter confirming the appointment, if it's not with Peter James, ring the hospital and speak with his secretary as soon as you can and explain what's happened, that you used C&B and got allocated to someone else but that you are a special case and in need of his particular expertise so can she please help by getting you reallocated to him.
I didn't realise you were using C&B else I would have cautioned you not to for this reason. It's a good system if you don't mind who you're going to see but not when you do! There was a story recently of a lady who used C&B to get an appointment to have her hip done and the appointments clerk allocated her to a foot surgeon! She didn't know until she turned up in clinic and he said "I don't do hips"! So she had to go all through the system again!
