I'm sorry, i have not heard of roommanager and can't give you any help. But we recently went to Little Hotelier and have found their training really good. They get you to connect to their computer and on the phone at the same time and they go through all the training with you. You actually see what's happening and can pull them up to quiz them about stuff relevent to you. They take the time for you to ask questions and are pretty thorough. So far, fingers crossed, it's all been smooth sailing. You get a free trial as well so no committing to it. Around the same price as roommanager too.
