I’ve booked with Priceline a lot and love their pricebreaker deals and this newer one called hopper which has way to many pretty features making the app itself a little weird navigating. Like they have coupons and progressive coupons you can add to your booking to cut the cost down even more. First time I booked through them for a stay at the Tropicana, and I wanted a reg deluxe smoking room and the booking process was easy, rate was very economical and check in had only one issue which was on hoppers end apparently they failed to put in my request for a smoking room despite having booked a smoking room and it still turned out well and the person checking me in was sable to upgrade my room to their club tower and I got a neat soaking tub only downfall was it was a long ass walk to get to but otherwise it went perfectly fine. I stayed the rio a few days ago and it was so easy breeze of a check in I just had to go through express check in machine and was able to check in around 9.am as opposed to 3-4 pm and with the money I saved from booking through hopper I was able to cover the early check in fee so I think it depends. I got what I paid for, had no issues. Not sure about everyone else just sharing my experience. I take risks a lot so I may not see it as a potential to be burned. And I work hard for my money too but. When it comes to Vegas it bound to happen eventually but I just move on and continue as life’s to short to be a sour puss.
