There is nothing better than a day with nicely spaced meetings
My current Project on every second wednesday:
10:00-10:30 Daily Standup
11:00-12:00 Architect Jour Fix
12:00-12:30 Lunchbreak
13:00-14:00 Sprint Retro
15:00-16:00 Sprint Planning
Most of the gaps have a reason (conflicting meetings, etc) We use those gaps to "transfer knowledge". That basically means we sit in the cafeteria chatting about work or non-work relatet stuff, planning our weekends, etc.
