Andy, if you are sure of your date of arrival, why not call B&H or Adorama, tell them what hotel you will stay at, and ask if you can have an order shipped to your hotel, to coincide with your arrival? That would be more certain than chancing on a Pentax 20 or 24 in a store. Tell the hotel to expect a parcel for you.
Alternatively, you could contact a store, give them your cc number, ask them to order and hold the lens for you, and pick it up when you get there. The DA 16-45 appeared 3-1/2 months ago, and it is again (or still?) backordered on B&H and Adorama. Pentax seems to be having trouble producing enough of these lenses to meet demand. So I wouldn't count on finding a DA 14 so early, unless it is very expensive. Have a nice trip. Joe
