The tour was informative and Ian was able to chear up the whole group in this freezing weather. We've managed to see most of the attractions with introduction, which is good.
While a suggestion that we'd better do a bit more intro on the buildings on 5th avenue, the guide has mentioned a lot names however we are keen to walk 1 or 2 blocks to go and see instead of just walking away to next stop. In terms of time management, I think we spent too much time on the ferry if we have to end the tour that early. Some of the churches, if possible, since they are not too big anyway and we are already outside, it worth giving a step in.
