Can we use our insulated bamboo cups on our next cruise?

Just off the Dream and we had probably the best weather we've ever had on Castaway Cay. We purchased a couple of the bamboo insulated cups while at Serenity Bay and were able to refill them with our favorite frozen cocktail on the ship. Supposedly it's like getting two drinks for the price of one when you have it refilled, but it goes pretty fast.
Can we bring these back on board and use them on our cruise we have scheduled in April?

Official policy is no....do people do it...yes. But I did hear they were cracking down on it.
