Im Going With My School Band On A 4 Day Trip To Disney World..?

I was wonder how bad the lines are around the next 2 weeks and what rides we should really ride and what others we should care less about. And if you know, how long the line might be. We only have a certain amount of time in all the parks except for the Magic Kingdom [we get to spend the whole day there] Also how much money do you think i should bring? Were going for 4 days, and we have to pay for our own lunches and snacks and we might want to buy a picture [from when we were on a ride] and souvenirs? Thank You!

School Band- Percussion?

Our school’s concert bass drum is in pitiful condition. We had to color it with a Magic Marker before the last concert to make it all the same color (sorta). Any ideas on how to get enough $$$ to buy a new one, or anyone know a company that sells them for a decent price?
