Not really a 'must have', but I take a small notebook and at the end of each day as I have my last cup of tea I do a page of the day's events and people.
Didn't think of the power strip, but have taken the hooks and duct tape!
Also, recently seen where AAA Auto Club has VISA card to preload and use instead of travelers checks. Am thinking about gettin one for each of us with just a couple of hundred on each, to use in ports. If stolen no hard damage can be done to any of our credit accounts.
