Depending on what you want and how much you could pack it carefully in your checked bags, decant it into containers of 3.2 oz or less and carry it on in your 3-1-1- bag or purchase it there. (You can carry on alcohol but you can't drink it onboard btw!).
Alternately you could use a grocery delivery service, we use we go shop and have also used garden grocer, both have been great. If you need more than just "beverages" this is ideal for a case of water, juice, milk we get cold breakfast items, fruit and snacks. Having breakfast in the room, drinks and such especially alcoholic drinks saves enough on the delivery fee and tip to make it worth our while, since we are usually a party of 6.
Another option is to hire a car service instead of using DME. With a round trip most companies offer a 30 minute grocery stop on the way to the resort, we just ask the driver if he/she can choose a store with a liquor store in the same plaza, then we divide and conquer. This will run about 130 r/t so its not as economical as a grocery deliver but you also get personal service to and from the airport and it saves about 30 minutes each way over DME.
