Knit socks, of course.
We went to the lovely Port Douglas for a week in the school holidays. Much more developed than when partner and I had gone some 25 years ago, but the four mile beach is still amazing to walk along in the morning and you can get a decent coffee at the end!
Unfortunately, it was a bit too windy to go out and snorkel on the reef, but a trip to Cape Tribulation was lovely and the general relaxing atmosphere and the ability to wear t-shirts everyday made the stay seem way too short.
I did have to have something to do on the long plane trip and in those quiet moments in the evening. Bliss.
