How to protect transmitted data via wifi in a hotel?

Question

WiFi

Hello!
I don't know where to write, so I'm writing here. I plan to go to Europe in September, see the countries and relax, because in the summer I didn’t manage to relax. A bunch of projects and so on.
The question is tormenting which SIM or what to buy to check data / sites on vacation. My comrades told me "Yes, there is wifi almost everywhere, connect and watch." But cookies can easily be intercepted?
How to be safe and what is better to buy for Internet access for Europe? I plan to check my projects, update the data - there you will need to enter the admin panel and so on.
