"Essential"
My Travel Essentials Kit contains a couple of Wine Bottle Stoppers. Better to buy wine by the bottle to drink on the balcony. It's cheaper than the mini-bar or room service, and with a Wine Bottle Stopper, I can usually fit the bottle into the mini-bar fridge: laid flat, and with no leaks.More wine now comes with screw-cap, but there are still a lot of corks out there. And it will usually work for Sparkling Wine, or a beer bottle, too.
