November should be pretty comfortable, but stick in a pair of jeans and a sweatshirt. No matter how hot it is, ac is a stinker, and it does get cool in the evenings (and when it rains). Another tip--SPACE BAGS! I pack like items together, squish out the air and, voila, more room for returning souviners. Not to mention it keeps the dirty from the clean. An added bonus is all your stuff doesn't get mussed when the airiport checkers go through your luggage since it's see through.
