Bonnie,
Really looking forward to the rest of your trip!
Re:"duck" tape; The Container Store sells Flat Packs of Duct Tape, easy to pack and available for these emergencies! I bought it last year and haven't had to use.
In 2001, We arrived in Dublin at the beginning of a month-long trip/cruise and DH's suitcase was partially ripped at the zipper. We did find "crazy glue" at the hardware store, but I would never have had the patience to do it as he did!
It has held well, as I have used this case on 2 subsequent cruises, so maybe "crazy glue" and flat pack duct tape should be in everyone's emergency stash!
