Not sure about the pools. We brought a bottle of vodka and a couple of bottles of wine in our luggage. We wrapped it in bubble wrap and then in a huge ziploc bag and strategically packed it. It came through with no problems. If you order orange juice through room service there is n/c. We ordered like 8 large glasses at a time and we had brought a big mug/cooler jug with us and mixed up drinks. I swear that their drinks that we ordered from the bar were watered down. So I found that drinking beer or wine was a better choice. In one of the ports we purchased a couple of beers and smuggled them in in our carry-on stuff. They were $1 a piece compared to the $3-4 on board so it was worth the risk of them confiscating. You can also purchase liquor in port. I think you're limited to 2 bottles each. You can check them when you reboard and they will deliver to your room when you are disembarking. We bought 2 huge bottles of absolute for like $25 which are like $40 each here so it was worth it to us to lug it back.
Good luck & enjoy!
