Egyptology is simply a branch of archaeology, so yes, you will absolutely cover the Egyptian pyramids in a general archaeology class. It will likely not spend a great deal of time on them, however, as a general archaeology class has a whole lot of a ground to cover in the ancient world, and Egypt only takes up a small part of that.

Then again, if your class deals specifically with a certain time in history, you might not cover the pyramids. As far as traveling, that has a great deal to do with money and your school's program. Some schools insist on fieldwork abroad, others do not. If your school is near places where fieldwork is being done, your school might not require much travel. If it isn't, you will likely have to travel, perhaps during breaks or summer for fieldwork.

In regard to the Seven Wonders of the World, the Seven Wonders of the Ancient World (which the pyramid at Giza is a part of) are largely gone. The Lighthouse at Alexandria and the Hanging Gardens of Babylon, all of them but the Great Giza Pyramid are gone. The other list you might be thinking of was created in the Middle Ages and contains the Leaning Tower of Pisa, the Great Wall of China and the Colosseum. You might very well go to Rome on an archaeological trip, so the Colosseum is a possibility.
