I probably book about 5-6 hotels a year for business trips, and as a small business owner I find http://www.hotelscombined.com saves me a lot of time mucking around to find a good hotel. Sometimes these trips are last minute so it's a real time saver searching the site and finding out which hotel website will give me the best price for where I want to stay at. I also find the site very easy to use, and has a lot of good options so I can easily filter the results down to what I'm looking for. Sometimes the images of the hotels aren't really clear, but other than that a highly recommended site.
