【题目】Passage2(2017届河北衡水中学高三七调)
Theme park getaways are popular with families, but they surely aren’t cheap. Happily, there are some golden rules of ticket-buying that apply to pretty much every theme park, and they can help you chip away at the cost of tickets. 1
●Buy tickets online.
Never ever pay the walk-up ticket price at a theme park. 2 .You’re guaranteed to save a significant sum-sometimes as much as $$ 20 per ticket-even for same-day tickets.
●Buy in advance.
3 .For instance, Knott’s Berry Farm in Buena Park, California, slices off $$25 per ticket when you make your purchase at least three days ahead.
● 4 .
This one is a universal no-brainer. Single-day ticket prices at Cedar Point in Sandusky, Ohio, are about 30 percent less than admission on Saturdays and Sundays. But the big bonus is that lines will be much shorter, allowing you to spend less time waiting in lines and more time having fun.
●Go in the afternoon.
5 .For example, Hershey park’s sunset tickets allow entry after 4 pm or 5 pm, depending on the day. You’ll still get between four to six hours of fun before the park closes, and you’ll pay up to 50 percent less than the full-day ticket price.
A. Avoid weekends.
B. Buy more tickets than you need.
C. Here are some ways to lower your theme park spending.
D. At larger parks, you’ll save money when you buy a package.
E. Instead, visit the theme park website and print out your tickets before you go.
F. Some/span> parks offer deeply discounted tickets for visitors arriving later in the day.
G. Most theme parks offer a price cut if you buy tickets at least a few days before you arrive.
