Boulangerie Patisserie in France will have lots of options for you. The croissants would bee a good choice since you don't have a refrigerator and I'd imagine the apple turnover would keep well, too. Without a refrigerator I would stay away with anything with cream inside it, but that's just me.
Kringla Bakeri og Cafe in Norway serve danishes that keep well. They have a cinnamon bun, too.
