The first thing that interests any tourist is the prices for accommodation in Dallas. They directly depend on the level of accommodation offered. So, the cost of living in Dallas in five-star hotels will cost at least 350 USD per night per person. In a four-star you can stay for 132 USD, but in some hotels rooms can cost the same price as five-star.
You can find cheap accommodation in Dallas in three-star hotels. In this case, you can find offers for 50 USD per night for one person. Approximately the same price on average is observed for accommodation for tourists in Dallas in one- and two-star hotels.
But in general, it is difficult to find something cheaper than 40 USD per night. Even wondering how much it costs to stay in Dallas in hostels, you are unlikely to find offers below 30 USD.
