Any further updates on this nvdre? I also booked this HOTWIRE rate over the weekend for a visit to Vegas in April, I'm trying to figure out the best way to follow up on this.
The fact that Hotwire is trying to play it off as though your reservation is valid for the 4 star MGM Grand when you booked a 5 star resort is unacceptable. This amounts to false advertising and bad business practices at the very least.
The way I see it Hotwire has 3 choices here:
1] provide a full refund [the very least they should do]
2] find alternative accommodation of the correct star rating with the appropriate amenities that you agreed to purchase when you bought the Hotrate
3] honour the booking [unlikely]
Best of luck nvdre, please keep us posted!
