I've heard about RumRunner flasks, but I'm leaving in a few days so I've wasted the necessary time to order. A local liquor store has hard plastic flasks, but I'm not sure how I could best use that. I'm also not sure if it's better to try and sneak some in my checked bag (NOT in the original bottle, but in a CocaCola bottle instead), my carry on (I've heard this may be the worst choice), OR just wait until we get into port on day 3 and buy something on land. If I do this, what is the best way to get it back onto the ship? What kind of security do you go through while re-boarding the ship in port? If I put it into a Coke bottle while on land, will they question me carrying a "Coke" bottle back on board?
