Husband and I just spent a week in Grand Cayman SMB first week of March. Liquor is very expensive on the island. We each took the allowed one liter per person of liquor (2 total) packed in our checked baggage wrapped in bubble wrap with no problem. We were able to find 'plastic' liter bottles of a brand we liked so this helped but others have traveled with glass successfully also. It definitely helped the pocket book as just our beer/soda/asti bill came to $173 which was more than our food bill for the week!!! (And we are not real heavy drinkers!) Glad we took what we did and we will do it again next year. Also, our property managers took a beer/etc. order from us prior to leaving and had it all ready for us in our unit refrig when we arrived at no extra charge. No need to stop at Liquor store on the way after traveling all day--we had our weeks supply.
Just remember you still need to declare on the customs form the liquor you are bringing in even if it is just the allowed amounts which are not subject to duty.
