I agree with my colleagues that alcohol in moderation is OK 2 weeks after surgery since you are off all medications. However, I have other concerns and advice that I hope you will consider.
First of all, you should follow your own surgeon's advice, since it is he or she you will go to if you have a problem, such as breast hematoma (bleeding), malposition (from too much activity or minor injury), or capsular contracture (bacteria or bleeding are the usual culprits).
At 2 weeks from surgery, your incisions are barely sealed (are all tiny crusts and scabs gone?) and exposure to pool or ocean bacteria can cause an infection, perhaps even one requiring removal of implant(s). Really!
Also, your pocket is certainly not durable enough to withstand vigorous activity, such as swimming, snorkeling, or even putting your luggage in an overhead bin! Some vacationers also like to engage in intimate activities that could cause a breast hematoma, and who would fix that while you are away from your surgeon in an exotic location without skilled plastic surgeon coverage?
Truly, I don't want to be the wet blanket on your vacation plans, but several months ago one of my breast lift plus implant patients went out on the town 18 days after her uneventful and wonderful-result surgery, became over-served at the bar she and friends were partying at, slipped in the parking lot and fell, popping open about 3 inches of her breast incision. Blood all over, and of course, her friends called an ambulance, which took her to the hospital where the ER doctor called me. (Add up the ambulance ride, the ER and ER doctor charges thus far.)
Since she was inebriated, we were unable to safely operate until the next morning (I was called at 3 AM), so she ended up going home anyway. I successfully re-operated (thankfully, her implant was not exposed, or I would have had to remove it), and she ended up with a good result in spite of herself (but she doubled her cost of that result).
I tell you this (true) story not to scare you or ruin your vacation plans, but to educate you. Please heed your surgeon's advice (and mine) to take it easy. If you can, you may wish to reconsider your plans for a couple of weeks later. Or modify your plans to include mostly quiet time under the umbrella with a good book and an occasional cocktail!
And, BTW, keep your scars out of the sun. They will turn permanently brown if they receive even a little ultraviolet while they are pink (6-12 months). Remember, good long-term results are worth the extra effort, and not worth the (premature) vacation activity you know you really shouldn't engage in! Best wishes and happy travels whenever and wherever you go!
