Thanks for the tips everyone. I hope they keep coming.
I leave on February 21st and will be there the 22nd-27th. I am hoping it will be enough off peak season that the lines aren't too long. But I think I will take your hint Tothill and buy my tickets online.
Yes, the fabric market is already on my to-do list. I am going to hit that on Saturday along with some parks and the canal district.
