I have used Skoosh, about a year and a half ago (Feb 2008), and everything was just fine. I was able to get a really great deal on my hotel. My experience was good, and yes, I would not hesitate to use them again.
You know what, I was just flipping through my paperwork for my trip next week and realized that I used gtahotels this time around and didn't even remember! Anyways... everything has been fine so far.
We have called the hotel to confirm ressies and everything seems to be in order. The website even sent us reminder emails with our confirmations just a few days ago. So, as long as everything goes well next week, I would recommend them as well.
