We had a trip planned for the last full week of March, which ultimately was cancelled due to the closures. We have 4 children, the youngest of which is 2 and he turns 3 in June. We have rescheduled the trip for October (we rented DVC points and did not have the option of a refund). Since we are travelling in October, do I need to purchase a ticket for my youngest since he will now be 3 at the date of travel?
