It's real and it worked! For me at least.
I was a little shocked that it worked and wasn't a scam. (I hadn't heard of the company previously.) I needed a hotel for one night prior to a flight, was booking at the last minute, and used Google to find a hotel near the airport with low rates. Hotelwiz was advertising rates for a Fairfield Marriott about 30% lower than the Marriott site. I called the hotel directly minutes after booking to be sure they had my reservation - and they did! Phew. No issues checking in either. A few minor issues I experienced: -During checkout, there was a last-minute step where I needed to confirm my country of residence (I was abroad booking this for the night before coming home so the site may have assumed my residence country based on my device location) and then the price changed when I switched my residence to the US. It was only a few dollars and likely had to do with taxes so not a big deal, but I would have preferred the step be earlier in the process so the correct price was displayed upfront. -We did have to pay an additional $3 or so upon check in. But for all I know this is standard in Mexico. We picked out hotel for being the cheapest option with a free airport to the shuttle, knowing that saving $15 on the room would be a silly trade off if we had to pay $40 for a taxi and be in a less comfortable hotel, so these minor fees didn't bother me under the circumstances. One fantastic piece of the Hotelwiz UX: I was sent a confirmation text with a link, where I was able to resend the confirmation email - and update the email address! Fantastic as I had accidentally missed a number in my email address. But also useful for folks traveling with others who may want to share the check in information.
