Capterra
Works well for us...
Pros
This software works with our channels and our dynamic pricing program. It took a long time to find a program that would do what we needed. OwnerRez does this well. It runs our units, plus it uses that information to make a custom website. Very cool. Tech support is second to none. I've worked with a lot of tech companies and it can take days to get an answer. I generally get answers to my questions within hours.
Cons
It's a lot to learn if you don't already understand the industry. The learning curve can be weeks. That said, when I had questions I was able to get answers quickly. So that helped.
