Smile, Say Cheese, A Little Laughter If You Please
This question gets asked often. I'm not one to encourage following the "photography/video spiel" because those spiels often change depending on who is speaking them. One employee (CM) in the RockNRollerCoaster pre-show area may say "no videotaping" of the Aerosmith band in the recording studio, and 5 minutes later after shift change, the next CM will not say that. Seeing as how you will be on a special trip, you don't have time to revisit attractions dozens of times like many of the people on this message board. With that said, shoot whatever you want. If you're not supposed to be shooting, you will be asked to stop. Unless you are grossly allergic to people asking you to stop, there's really no reason to hold back.
If you are able to shoot digitally, do that. If you don't have a digital camera, now is a good time to invest. Unless you are a professional or experienced photographer, you will get home, have your film developed only to result in disappointment and all that money wasted on film processing and printing. The possibility of disappointment is ten-fold with indoor photography (especially if you are not using flash.) You want to enjoy your time, not worry about fiddling with aperature settings, ISO, manual focus in dark rides, etc.
Also, I would suggest having a couple high quality disposable cameras. Keep them in your pocket so you can grab a candid moment without having to set up a more complicated camera.
Don't forget that you can buy photo books and DVD videos of parks and attractions. The pro's already did the work, and you get to bring home the results.
Alot of people make the easy mistake of photographing their environment more than photographing themselves. In the end, it's the "people pictures" that are cherished, and the attractions pictures usually find their way into a shoebox under the bed.
So, #1 tip of the day: focus your picture taking on the people in your group - and make sure you hand off the camera so they get some shots of you too. Also, do the majority of your picture taking outdoors.
Tip #2: Bring all of your own supplies - batteries, film, memory cards, etc. They are available on property, but it will cost you more.
Tip #3: If flying, keep your film in your carry on baggage. Stronger x-ray machines for check-In luggage machines have been proven to ruin film. Also, if you're traviling with 800 ISO film, or just very careful with your film, current FAA regulations provide for all passengers the right to have their film hand-inspected and avoid x-rays. It's your call.
