I am planning a trip to Disney with my Girl Scout troop (I'm a leader) and while there they want to volunteer at Give Kids the World. Now, I'm looking to transport 13 girls and 4 adults from Cincinnati to Disney in the most economical way possible. We're looking into driving 3 minivans because airline costs are just too high. My question is this....does anyone have any experience using a charter bus? Any idea how much it would cost - obviously approximates. This is appealing because then we can all travel together and someone else is doing the driving!
