I always thought that the word "retreat" was a lousy moniker for what firms do to reconnect with colleagues, recharge their batteries and plot their next strategic moves. Dictionary.com defines "retreat" as:
1. the forced or strategic withdrawal of an army or an armed force before an enemy, or the withdrawing of a naval force from action.
2. the act of withdrawing, as into safety or privacy; retirement; seclusion.
1. An "Advance" is a retreat with a purpose
2. Set the right tone
3. Provide a variety of opportunities for interaction
