I personally would go on to
Walt Disney World Resort and price the exact package that you have been quoted on and compare. Disney has that great offer of buy 4 nights get 3 with also a $200 gift card at sometimes. I have always just booked straight through Disney and will always continue to. I do receive the emails from
MouseSavers.com - Disney Discount Source - Disney World Discounts, Disneyland Discounts, Disney Cruise Discounts with discount codes and that should be of help to you as well.
