S.B.
Call Legoland, explain the situation as ask if they have any comp tickets available if you were to request on your school letterhead. You might be too late on the timing for this year but at least you will find out for future years. If that doesn't work, ask them to steer you to discounts that might be available. Tickets with a local soft drink can or special rates for children. You could also google Legoland discounts or coupons and probably come up with a list. I think Costco had Legoland tickets at a discounted rate last year. Good luck with your search.
