This depends on when you book in conjunction with when you depart. With Disney World and Disneyland all that is required is a $200 deposit to get started. You then have up to 30 days prior to departure to pay the balance off. Disney Cruise Line requires a 20% deposit and the balance is typically due 45-120 days in advance depending on your itinerary. All other suppliers work the same way, requiring a small deposit and balance due later. You have the option of making payments on your vacation or paying the balance all at once when it’s due. If you book within a 30 or sometimes 60 day window, payment in full is due at time of booking.
