Can i get some fun park tips?

My family and i are going to an amusement park later on and i want to take better pics than i did yesterday

i have two strikes against me from the start…

1. With the crowds they have a tripod is not feasible

2. We can't stay until nightfall, my niece's baby has to be home much earlier than that

so, that being said, how should i go about getting good shots, action shots for instance ie rides etc?

i use a Nikon D7100, i have an 18 to 105, 85mm micro, and 55 to 200 telephoto lens to work with as as well as a remote shutter release. I have a mini tripod but i just do not think it will work with so many people around, plus a tripod will draw more attention, which i do not want

Think DETAILS. Get in close and shoot things that "say" amusement park, but you do not have to try to capture vast areas. Shooting details will, in most cases, also eliminate having people in the shot. Shoot things such as the wheel of a ride, close up of a candy apple, cotton candy being whipped up, someone holding a ticket with the park name on it, look for structures that have interest when looking UP, in other words, get low and shoot up, such as intricate supports and interesting signs. When you have crowd problems, change your mindset from getting the big view to getting the small view.

As this in in daylight, you have no need for a tripod unless you wanted to use a slow shutter speed to try to depict movement, in which case you would also need a strong neutral density filter.

Work handheld and look for DETAILS.

Set your ISO to 400 or higher so you can get a fast shutter speed. The faster the shutter the more action you can freeze. Use a large aperture (2, 2.8, as wide as your lens goes). Try to time the shutter release to the action-i.e. When the car comes around and you can see the faces of the riders, at the moment the roller coaster reaches the top of the loop, etc. Pre-focus and let the action come into the frame where you want it - trying to follow it is very difficult to time correctly.

Action shots can look more exciting if they have a little motion blur. This requires a slower shutter speed, which can be a problem if you're hand holding the camera. Look for solid stationary objects (trash cans and fence posts work very well) and set the camera on it. Frame up from there, and remember you can crop. Not every shot that comes out of the camera is perfect. Remember to reset your ISO if necessary to slow your shutter down-you'll be shooting in bright daylight and this can be tricky.

Also if you have a safe place to leave the gear (NOT the car!) jettison some of the gear. You don't need to carry the minipod and the 18-105. The 55-200 will do the job. Have somebody hold it if you're going on a ride. The 85 macro (not micro) will come in handy if you want to shoot while on some of the rides. The octupus ride is great for this trick-use the 85, focus on the place another pod/car will be, have your family in that pod/car, and when the car comes into position shoot the picture with the flash and a shutter speed of no more than 1/60. You'll freeze the people with the flash, but the longish shutter speed will give you some motion blur at the speed you and they are moving.
