They do sell energy drinks, but not Red Bull to my knowlege. Disney contracts with Coca Cola, so it will be whatever energy drink Coca Cola is shilling.
You can not get them at the parks, but Universal sales them for about $4 a can, so it is way too expensive!!
I have Marge at WeGoShop.com deliver my 12 pack of Red Bulls to the Wilderness Lodge on the day of our arrival, she is GREAT & I also get a few more groceries !!!
You can get the big (16oz) cans of Monster from the resorts, and they also count as a snack credit as well if you are on the DDP. Not sure if it is widely available in the parks though
1. You can not place in a carry on because it is a liquid.
2. If you place a 12 pack in your suitcase (I did this one year), it REALLY forces your suitcase to exceed the allotted 50 pounds & then you have to pay the overlimit fees. By the time you have done that, you could have paid Marge from WeGoShop.com to deliver you a 12 or 24 pack of RedBulls with some addl groceries.
DH is also a big red bull drinker and you can get it when you go to the DTD westside bus stop and just walk across the street to the gas station store there. They have them at a decent price. DH bought enough for the week at the begining of our trip. The store is also good if you like to have milk or other items for the week and don't want to pay the expensive prices at the resort stores.
I too HAVE to have my RedBull in the morning, it is my coffee !!! I have it delivered by the case to my hotel room by WeGoShop.com, Marge is great & she also deliveres our breakfast items & water.
I did not realize this was an older thread, sorry, I had already previously posted, my bad.
