Cast aside your doubts, I've been to different parts of Europe a few times with different, healthy MBPs (I buy a new one every 4-5 years) with healthy adapters.
Plugging into the wide EU outlet with the Apple-manufactured plug, from the "World Travel Adapter Kit", can lead to uncomfortable "vibration" that you feel when you touch the top case, depending on the the hotel/airbnb. Whenever I visit I expect I should charge while I'm not using the device.
