1. Choose a theme park you might want to go to.
Choose your parks carefully. You may want to see if it has restaurants, the rides that suit you, souvenir stands, etc. You don't want to be bored at an amusement park, because usually if you're happy at a theme park then you will have the best time ever. You may want to ask your friends' opinion and facts about the park. Tell them to list the pros and cons of the park. Be sure to write it down.
2. Print out a direction map for the theme park.
If you know where it is, you might not need a map. But the benefit of getting a map is that if it shows a busy route, you can find another route to go to so you can get there earlier. Some sites that can help are Mapquest, Yahoo Maps, and Maps.com.
3. You can plan ahead, bring coolers packed with frozen water to keep your food cold and you can have a cold drink too!
Eat a good breakfast but not heavy as you want to be light on your feet. This way you will spend less time in lines in the park. Other things to bring are cameras, sunglasses, and extra towels. (Most corporate parks, such as Six Flags, Cedar Fair, and Disney, do not allow outside food and drink, unless it's water. Always check signs outside the park, or the park's website before you go.) However, those with diabetes are allowed to bring juice in case their blood sugar gets low.
4. Get things to make you comfortable.
Pack up stuff you might need on your trip like money to spend on food. Also you might want suntan lotion if it gets too sunny. If the kids want to go to a little kids ride you don't like, you can read a book while they are riding. Make sure you have shoes that are comfortable. Theme parks are usually spread out all over the place, and they are huge.
5. Drive all the way to the theme park.
Use the map. If the park is far away then you should bring things to keep you and your kids and friends satisfied if you have them.
