     Are you planning your first visit to a music festival? This article offers insights (洞察力) into what you

might expect to find as well as some tips on how to make the most of your day.

     Having experienced a large number of festivals, I feel that I'm in a good position to be able to discuss

the advantages and disadvantages of such occasions. So let's begin by discussing the advantages. Why

are there so many people attending festivals each year?

     One obvious reason is that the festivals attract a wide range of bands and stars. That means that you

can often see many bands in a single weekend. Besides being great fun, this can also save you a lot of

money when compared to seeing each of the stars individually. Some would say that this cost saving is

hard to find these days, with the prices of festival tickets rising. Though this is true to some degree, you

can still find bargains if you look for them.

     You'll also find yourself mixing with a lot of people who are interested in the same types of music as

you. After all, that's mainly why people go to festivals -to hear music.

     Are there disadvantages too? There are some, but many of them probably won't come as a surprise.

Organizers know that they have a spellbound (被迷住的) audience, and so tend to charge higher prices

for food and drink at the festival site. You might want to limit how much you consume or find cheaper

things.

     Also, getting a view of your favorite band may not be easy. It depends on the location of the festival

and how popular it is. If you really want to see a particular act, try and get to the area where it's playing

early.

     Finally, do remember that it can be extremely exciting right at the front when a band is on stage.

     All in all, there are far more advantages than disadvantages. Enjoy your first visit to a music festival!
