The is a bar at CBR right? Can dh walk there, get us each a drink, and bring them back to the room?
Yes, there is a bar and I believe almost every bar in wdw is always willing to give you the drink to go.
Yes, there is an outdoor bar next to main pool that has full offerings (beer - draft/cans, wine, liquor), you can also purchase beer/wine from gift shop (cheapest option for bulk onsite) or the QS restaurant has single offerings (beer/wine).
I wish I would have known about the ability to take drinks to go elsewhere on property. I'm from New Orleans so the last time I was out of town and asked for a "go cup", the bartender looked at me like I had 3 heads. So now I don't even bother unless I actually see other people doing the same.
Also, we sat at the Banana Cabana @ CBR for a few drinks, and they opened a bottle of wine that we didn't have an opener for so we didn't have to purchase a $200 wine opener from Disney!
