Should Brazil and Argentina travel with their own electric water bottles?

Hotels in Argentina, Brazil don't provide hot water, and generally you can't find it.

Even if you ask them for hot water, if you don't speak clearly, they will find it difficult to give you hot water, and they can't even make instant noodles.

So if you must eat instant noodles and make tea with hot water, you must bring a hot kettle.

Some hotels have kitchens and don't need gas stoves and hot water bottles.
