People are sharing their frustrations on social media platforms like TikTok and Reddit.

Travelers post videos of their hot hotel rooms, making fun of the lack of air conditioning in expensive hotels in cities like Paris and Rome.

Tourists are visiting Rome, Italy.

There are also extra costs that travelers do not expect.

Some hotels in southern Europe charge extra for air conditioning, which can be around 10 to 15 euros per night.

In July, temperatures were very high in France, Spain, and other countries, due to a heatwave.

Europe is getting hotter faster than other parts of the world.

Not many hotels in Europe have air conditioning, which is different from the US and Japan.

Many hotels are in old buildings, which makes it hard to add air conditioning.

Adding air conditioning to very old buildings can be too expensive or not possible.

Old European buildings were made to keep warm in the winter.

Some experts say that old homes in England and France can get very hot because they were built to keep warm.

Even if hotels want to install new cooling systems, there are rules that make it hard.

The European Union wants to stop using certain cooling agents that harm the environment by 2050.

Because these problems will take time to solve, travelers need to be prepared for the heat.

To have a comfortable trip, planning is very important.

Travelers should check if their hotel room has air conditioning and ask if it costs extra.

It's also a good idea to pack light clothes, portable fans, and cooling towels.

Travelers could also plan their trips for times of the year when it's not as hot, like May or September.
