SiteMinder

It has many features and it is widely recognized by different OTAS and PMS systems. It is very complete system and relatively straightforward to use.

Some features are a bit complicated to operate and then you would need to see a tutorial or contact customer support to understand the procedure.

I have been using Siteminder for quite a while now and it has proved to be one of the most robust channel management softwares for the hotels. Here's how I am going to break down the Pro's of Siteminder :

1- Simple and Easy to Use
2- Supports many big, mid-size and small OTA's.
3. Reservation & Yield reports.
4. Connectivity with multiple Property Management Systems.
5. It's definitely cost-effective
6. Easy to set-up rooms, rate plans and map them.

Apart from all the good things mentioned above Siteminder still needs improvement in certain areas. The thing that I like the least about them are as follows :

1. Customer Support is terrible and very rarely would you get a first call resolution.
2. GDS by Siteminder is not being managed efficiently, the staff seems to have very little information on how GDS works.
3. Their turn around and on-boarding time sometimes take weeks.

Tons of integrations, at a pretty much fixed price. Lots of others charges per reservation, per connection, or whatever, but Siteminder only charges per room. Nothing else. It's super clear and transparent.

Interface is fairly easy to use. I especially like that you can choose to resend a failed reservation, which usually fixes any problems.

In general, Siteminder rarely causes problems, and there's very little I need to contact support about.

It still functions as a middle-man. Lots of new PMSs are offering integrated Channel Managers, and they will be more native, which will inherently have an advantage over traditional Channel Managers.

Another thing is there support is super slow. You have to submit a ticket and wait for them to get back to you. Good thing though is that there is VERY little I had ever needed to contact them about.

A few connections I'd like to see a better connection with, in particular HostelWorld and HotelTonight.

Very complete Channel Manager with everything you need to run several properties mapped through different OTAs.
Working properly, never had a real issue.
Their customer support got back to us promptly each time we had a problem in understanding something or for a set up.
Like some says it's easy to use when you know what you're doing.
It's a very professional Channel Manager.
The price is also professional but nothing surprising when you have stability and efficiency.
I would definitely recommend it.

Like I said above, it's a very professional Channel Manager so you should expect having troubles understanding what should be done and what should be left untouched.
That has been the major issue for us, to understand what to manage and what not to touch.
We didn't have the experience we have now with channel managers so as profanes it was pretty hard to do the set up.
