One of my favorite places for a vacation is Mexico.I really like the weather because it never gets cold there.The people are very nice,too. They never laugh at my bad Spanish. And the food is wonderful!
Mexico City is a very interesting place to visit. It has some great museums and lots of fascinating old buildings.And the hotels are not too expensive. But you can stay in other places in Mexico. For example, you should go to one of the beach resorts - like Acapulco. And you shouldn't miss the Mayan temples near Merida.
