I'm off to New York in June, with the breadknife, 65th Birthday present to myself. Last time I was there was 1974 & again 1978. Obviously things have changed. I have a fair idea of what we would like to see from a tourist point of view. The question is, book all the excursions before we go, or do our own thing when we get there? I have read a number of horror stories regarding pre-booking a block of excursions etc. Any advice from recent travellers would be appreciated.
