You will also want to check out some of the shows along with the rides. You have Emerald Beat in Ireland, the Pet Shenanigans show and definitely This is Oktoberfest at Das Festhaus.
You will want to try to get to Das Festhaus around 30 minutes before the show, so you can find a place to sit and get your food. The best place to sit to see the most is on either side of the stage. The dancers even grab kids and people from the audience to dance. The deserts are to die for and all the food at Busch Gardens is made fresh at the park everyday including the pasta in Italy.
They do offer a Quick Queue option for the rides. There are now two different Quick Queue options. The first is the normal Quick Queue which costs $14.95 and lets you go to each ride once using it. They now offer an unlimited Quick Queue that allows you to use the Quick Queue line on every ride as many times as you want for that day. The unlimited Quick Queue is $39.95. Alpengiest and Apollo's Chariot have set the second row of the coasters aside for Quick Queue.
