What to do for a two hour bus ride?

In about three weeks, my schools music department is going on a field trip. Early in the morning(6:30am) we're leaving on a 1-2hr bus ride to a high school where the music competition will be held. After that, we have another thirty minute ride to Kings Dominion.
The chorus boys have to perform in their concert attire(tuxedo shirt minus the coat) so we will be bringing our garment bags with a change of clothes for the park. The bus ride home will be two hours in the dark. This is what I'm bringing to pass the time-

-my iPhone 4
-psp 2000
-book and reading light
-pillow pet

Any other recommendations? Free iPhone apps would be greatly appreciated

A drink
a sandwich

Headphones + Pandora radio = big help in making the time pass

as for games i don't know =/

if you haven't tried the game 4 pics 1 word that one's somewhat fun for passing time

Book sounds the best, Something like Game of Thrones.

Shame hardly anyone reads anymore.

Lots of food. Headphones. Temple Run 2, Mega Run, line runner 2

Honestly that isn't much time at all! I mean I have been on a 9 hour journey before in a car stuck sitting in the middle which is very uncomfortable to sit in for hours on end! And honestly for that journey all I needed was my earphones, hours worth of good music on my I-phone to listen to and possibly some films on their as well. Oh and of course a portable charger for my phone so it didn't run out whilst I was their. But seriously it should be easy for you to occupy yourself on a 2 hour journey on a bus: )

Jeez, it's only a two-hour ride. You'll live.

Sounds like you've got everything.plus it's less than 3 hours. You'll be surprised how quickly time passes. For your iPhone, try the Rounds Hangout app (http://www.rounds.com ) - it's fun. You can take pics of yourself in your tux shirt and write stuff on the pics and send them to friends.

Well if you can, some paper and a pencil and I pen to draw. Even if you can't draw for your life just scribble stuff, its very fun ( trust me I do it all the time )
