Here's a different one, which appears like you don't even need to have an American Express card to use:https://www.privilegestravel.com/en/login/

This one works differently than most OTAs that I am used to, because you pretty much have to sign in to see anything. There is a little bit that you can browse without signing up for an account, but not much.

The kicker is that you can create an account for free, and they give you $150 in Travel Savings Credits right off the bat. Looking around, you can use those on Hotels, and Cruises.

I haven't heard much about it yet, but it looks pretty good. Any one else use them yet? Were there any additional savings if you were an American Express cardholder vs not?
