Thought I would post my experience of using Club1 as I did review this thread prior to booking with them and was nervous about the booking!

I needed a hotel in Newbury UK for my partners work Christmas do, unfortunately this coincided with the hennessey gold cup (now Ladbroke trophy I think!) and the best I could find was the Double Tree at Newbury North for £185 with the hilton honors discount. I saw on one of the travel blogs sites that club1 were doing free membership over the Black Friday weekend, so I thought it was worth a go. I was quite surprised to see Club1 could get me the same hotel for $88 and I snapped it up. I didn't receive any email notification through as a result of joining or as a result of my booking and I was feeling quite nervous, so I rang the double tree who told me there was no record of my booking! I completed the contact form to club1 to find out what had happened but had not received a response two days later and rang them. The person I spoke to promised to find out and email me within half an hour. I waited two hours and had not received a response, however checked my junk mail on the off chance and there were all the emails, responses from club1 and more importantly the hotel reservation number. I rang the hotel again and this time they did have the reservation (one of the emails stated that it could take 1 or 2 working days for a booking to be confirmed).

We stayed at the hotel last night without problem and although (even excluding the emails arriving in my junk mail which is my fault), the process wasn't seamless I certainly will be checking their rates before making any future bookings. I have no idea how they achieved the level of discount they did but certainly am not going to knock it!
