Oops, I made an error in my original post. My suggestion was: "Marriott ban those under 18 years of age from using serenity pools". I meant to say, ban anyone under 21 years of age or the legal drinking age of the country visited. Attaining the legal age, typically age 21 in the US, should eliminate any underage alcoholic consumption and associated issues. Serenity pools would then have a greater propensity to be calm, peaceful, tranquil, relaxing, and quiet, as the name implies. If a Msrriott resort has a serenity pool, it would have other pools on-site as well. Finally, Marriott needs to provide pool oversight and route any offenders to more appropriate pools. What do you think?
