Just one bag - for the NOLA weekend and the tour of Australia - and did not check luggage for any of these flights.
Still using the bag I mention in the book, and it's holding up great even though I sort of beat the crap out of it.
For longer trips, I'm definitely feeling powdered laundry detergent rather than shampoo. Works better, actually smells like you did laundry.
I packed only two dress shirts for the 10 workshops in Australia, so made use of hotel laundry service for crisp ironing.
Discovered what I think is my favorite part of Australia - the southwest. It's got everything, forest hikes, spelunking, boring vineyard tours, great beaches (google "Denmark elephant rock" and be awed).
