My plans for the summer holidays

I'm going to Miami,Orlando (United States of America) and Bahamas with my father,my mother, my brother, my grandma, but my grandma can only go to the cruise because she is older and she can't walk too long because in Orlando is Disney and in Disney you have to walk a lot and in some occasions you have to run and my grandma can't run.
I'm going to the airport in the planes of American airlines.I'm going to do three stops over in the plane: first,to Miami,Orlando and Montevideo.After that I'm going to Miami,then in cruise to Bahamas and to Montevideo by plane.
