This is a must have for anyone who goes on an all inclusive vacation and enjoys to binge drink while away. It's actually brilliant because it saves you from multiple trips to the bar. I am unsure to why they serve drinks in a dinky little plastic cup, like you can literally finish your drink in 2 gulps. Check out this awesome cup I purchased from a local beach walker. What makes this particular mug extra special is that it has a straw hole and a lid so no bugs or sand grains can sneak into your drunk. Pure genius!
