Hotel Booking System anyone?

Hey kirupians,

So I’ve got a hotel website to dev (front and back), and I’m going to have to implement some kind of reservation module with secure payment and all the works. Building the website and CMS is pretty straightforward, it’s the reservation stuff I’m not so sure about.
Does anyone have any experience with that kind of development or know about any services I could use ?
I had a look on google and found a few paying services and modules, but I’d like to know what you guys think before I make my move.
