It is in your best interest to have the person doing your travel to check the charges for EACH room at Disney.
If you have more than two 18 year old students in the same room there are additional charges for that room per day. I saved our team $500.00 by changing who is in which room to make sure that there are no more than two 18 year olds.
I understand thier rules, but question the application to the robotics FIRST competition as many students are 18 year old seniors.
