A good hint I used last trip is to, right when your laser becomes activated, shoot at nothing and see where your laser is. If it's slightly to the left or right, you can adjust your aim. There are some hidden targets. i managed to get over 100,000 twice.
My parents went with us on our last trip and they were in wheelchairs. They had to stop the ride for them to get on. Afterwards, my mom said how bad she felt because the ride was stopped. I told her not to worry, it is a wonderful thing when Buzz stops, no one was complaining (except maybe the ones who just got on it .
