Traveling during the summer vocation has advangages as well as disadvanges.Stuents have lots of time to spend and they don't need to worry about time.But there are too many people when we travel during our summer vocation.And it is hot,too.What's more,the tickets are more expensive especially the famous sighseeings.Sometimes there are so many people that we can't enjoy the beautiful scenery and the food.Sometimes It's hard for us to book a hotel.
