My star rating is based on how efficiently they handled my complaint. I booked a weekend getaway to a nearby resort for my boyfriend and I. I called the hotel one week in advance of our arrival to confirm our reservations but they had nothing on file for us, citing that they weren't sure if Groupon ever sent them our travel details at all. Worst of all the hotel was overbooked and they couldn't accommodate us even if we provided them the details of our Groupon purchase. When I called Groupon on Monday morning I was placed on hold for 30 minutes (room for improvement there) but the person I finally spoke to about receiving a refund was courteous, sympathetic and most importantly prompt about contacting the hotel and then issuing a full refund to my credit card, no questions asked. While I am iffy about whether or not I will book travel with Groupon again I will say that they were extremely prompt and efficient in solving my issue.
