School Holidays Trip to Orlando

My sister in law is going to organize a trip to Orlando for their school holidays this year end. She plans for a 8 days 7 nights trip some where in December. Her class is about 35 students. She is going to ask everybody to join the trip including their lectures. Looks like that will be a big group traveling plan. She should request group hotel during the vacations. She is to in charge of all the vacation schedule, traveling points, hotel reservation, air flights and meals. Awesome! It's not an easy job especially it's come to a group planning. I do hope that she can handle it and goes smoothly to enjoy the trip.
