Because people used to give first priority to their comfort. But the fact is true traveller may not go for it. Travel it self is the new exploration of life. But most of the people don't know about it so they go for hospitality and waste a lot money in it.
Each to their own. Some people romanticize travel in the most ruggard way. And others don't. I have spent any where from couple of hundred Rs to over a lakh per day on trips. Nothing wrong with either approach. Everyone had their priorities and no one has the right to judge what others spend on
Hospitality comes in the form of service provided to guests.While traveling to places people want their stay to be memorable and that is what comes through great hospitality.People would return back to the same place if they are treated with good hospitality
I have been through both kind of travelling within my comfort zone and out of my comfort...with luxury and backpacking...definitely exploring the place is best done when out of your comfort zone but I do have set of friends who look for good hospitality first while planning trip..so I guess it's depends on the type of traveller you are.
