Thanks Paul for this topic, it's always a good one.
A lot of what's been suggested I do and I do it because of cruising these postings!
Things like flourescent duct tape on the handles of my luggage, bungie cords to keep the balcony door open, multi-outlet adapter for the electrical outlet, batteries, folded rain ponchos from the sporting good store (about 3"X4" good for one time use), a packpack for shore trips.
We also bring snacks, diet sodas and peligrinos packed in large zip lock bags that we place in a rolling carry-on size suitcase. On the way home the suitcase doubles as a souveigner (sp?) bag.
Please everyone.......keep em comin'.
