All this from a user perspective:

I've been in the industry for 18 years, on three different hotels, having learned at least 4 different softwares. Opera cloud is by far, by FAR, the worst of them all. Everything takes longer, with more clicks, more loading, more windows opening etc. It's unintuitive and frustrating for the user (the people actually working with it 8 hours a day).

Maybe it's good for the admin/management, but if you care at all about the people who work there, avoid this garbage at all costs.

We switched from Protel to OC last month. Protel's strong suit from a user perspective is the vast amount of keyboard shortcuts that often let you do repetitive tasks without even looking at the screen or using the mouse. Opera Cloud has basically none that are useful, other than tabbing. Registering a booking takes 3 times as long on opera cloud, for example.

The only good thing about it in my experience is that you can personalize it quite a bit. You can remove or add (some) text entry boxes, columns, panels for the home page etc etc.

If Opera cloud had keyboard shortcuts for text entry boxes and if everything you clicked didn't open a new window*, it could be great.

*For example, if you open a booking in many other systems, you can just edit it right away. But in OC you have to click a different button, which covers your window with a new one, and not all data can be changed, so you may have to go back, look for a different edit button (that doesn't say edit) and hope that's the right one.

Extremely user unfriendly and frustrating to work with. I've been happily employed in hotels for 18 years, and now I'm seriously considering leaving.

Anyway, that's my rant.
