Lovely factory - very unique and worth a visit! We had a chance to visit the factory during off hours. It's a lovely little factory that produces nice works. My mother is a batik artist and we've seen batik all over the world so we were happy to be able to see it.
The best time to visit New York, weather-wise, is the spring season (April-June) or late summer and early autumn months (September and October) with temperatures ranging from 50 to 64 degrees Fahrenheit. However, bear in mind that spring and autumn are traditionally the most crowded and expensive months of the year.
Hotel seasons. Hotels in New York City are cheapest from mid January through March, but relative bargains are possible almost any time of year. Booking as far as possible in advance is usually the best strategy, though sometimes prices do come down as the dates approach if rooms are not booked and demand is weak.
