I engaged TravelUp via a multi-cite venue. The price was quite enticing. Then I found out that the hotel stay needed to be paid a week before my arrival. This seemed quite fishy to me. I verified a room was reserved for me and assumed everything was being handled appropriately. In the end, everything was perfect. Their website was a bit out of kilter when I tried to pay, but ultimately all problems were resolved. Will I use them again? Yes... if the price is right.
