According to the SPI Online Contract of Terms and Conditions, sections 18, 19, and 20, as well as at the top of (and throughout) the Standard of Conduct, we address this issue. Since this trip is not at all associated with the school where I work, I base my policies on the SPI company's policies. At the most, I am upholding my own moral standards for the best behavior of our group. At the least, I am upholding American laws.
Please let me know if you want to personally talk to me about this topic, but, as far as official statements go, alcohol consumption is a no-tolerance issue for me!
Always seeking to ensure the safest and best experience for the group,
Laura :)
