Tip # 1:
Carpool to the cemetery.
If you have space in your car, let your other relatives ride with you, or ride with them. It doesn't make sense to bring one car each if you can squeeze into one car. If you live far from your relatives, you can leave your car at their place or vice versa, then carpool to the cemetery. Not only are you saving on parking space, you're one less car on the road, and of course, you have a smaller carbon footprint
Tip # 2:
Bring your own food
Bringing your own food means food will definitely be cheaper. It's funny how food prices inflate inside the cemetery. When you buy food in the cemetery or outside the cemetery, you'll be using plastic spoons and forks, plastic/paper/styro plates and bowls, plastic/paper/styro cups and not to mention, using a plastic or paper bag to carry everything you bought
Tip # 3:
Bring your own drink
Reduce the use of plastic bottles. It's just so wrong in many ways. Nufsed.
Tip # 4:
Use washable utensils
Don't be too lazy and buy paper plates and plastic cups. Bring the sturdy plastic ones. You can bring water for washing the plates. Just rinse the flat- and silverware with water and wash them properly at home
Tip # 5:
Instead of using your gadgets while passing the time in the cemetery, mingle with your family or go spelunking with your cousins. We once played hide and seek in the cemetery. It was so fun :)
