Travel insurance
Check whether your bank card or home insurance already covers this trip.

Your own plan's EU roaming may already cover this.
Renting a pocket Wi-Fi is the other common way to stay connected.
These are sites people in book with. Each opens in a new tab, on the site's own pages. Some pay us a commission if you book, at no extra cost to you; most pay nothing, and what a site pays never decides whether it is listed or where.

Crowds is a score out of 100 where higher is quieter. It counts public-holiday clusters in TR as well as at Brussels, which is why this table differs from the same one read from another country. A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. Crowds alone never make a month “avoid”: that is reserved for weather worth skipping.
