This chapter discusses the challenges and rewards of conducting field experiments by sharing the details that went into conducting several large-scale field experiments within hotels. In discussion of the studies, we document three stages of conducting field experiments with outside organizations. The first stage is devoted to advice on outreach, including communication strategies to reach potential organizations. The second stage refers to securing buy-in from key stakeholders and organization partners. Lastly, we detail methodological advice in the implementation stage by highlighting potential concerns and safeguards.
