What are the realistic alternatives to Booking.com though? When I'm planning a journey the reviews and search by area features of Booking.com make it possible for me to gain some understanding of going rates and hotel quality, but the process leaves a lot to be desired for both me, the customer, and the hotel. I can search with Booking.com yet book directly with the hotel, but that means I can't review the property and help others.
