I can only speak from personal experience (perhaps our Scrum consultant did it wrong). We have a large group and even running through the all of the demos (mostly slides really) from all of the teams at the end of a three week period took days. Added to this the retrospective, multiple planning sessions as well as all of the meetings that we used to have prior to doing this. In the end, it was just so obviously unworkable to everyone it had to be stopped. However, you are absolutely right, we were not in meetings 100% of the time - it just felt like it. Many people need good swaths of uninterrupted time (perhaps 1.5-2 hours minimum) in order to be productive. Rapid context switching between various meetings and development work can be expensive. It is unfortunate when this time can only be found outside of working hours. My suggestion is to start with no process and no regular meetings and carefully add process/meetings as required. If you need to talk with one or more people... call them right now (or arrange a meeting with a clear agenda - right now). All overhead should be carefully evaluated in terms of its actual ROI.
