I used Hotels.com to get my rooms in New Mexico and in Texas. They were very helpful, but when the "promise" to get you a free stay after 10 nights will never be. I booked 2 rooms for 6 nights, my math = 12 nights? SO far I have had added only 4 nights. Their web page is as BOGUS as can be, run around after run around. Then you call the 1-800 number and talked to some poor guy who could not understand my American English? Why offer something "free" after using their system, only to give you extra poor service. I am sorry, but HOTELS.COM needs to take care of their customers if they want good reviews. USE TRAVIGO or SOMEONE ELSE!
