It would be great is someone would make such a website for Barcelona hotels, I have to travel there the next month and cannot find the cheapest hotel rate. I am sure your initiative will have a lot of success, a lot of people travel in Las Vegas and listing the cheapest Las Vegas hotel rates would help them a lot.
Hotel rates vary from place to place depending on their location and the services they offer. However, a cheap hotel room is a budget travel must, and there are several places to find the best of the bunch. I would recommend you to search online for hotels rate in Las Vegas.
