This has been independently confirmed with three separate people from Disney resorts. The official notice is set to go out tomorrow. Starting August 19th, all Disney Dining Packages (quick service, dining, deluxe, premium, platinum) will be able to be reloaded for the meal and snack portions after arrival. You will only be able to reload after one full day of coupons have been used (like for regular dining you must have used 1 table, 1 quick, and 1 snack for everyone in the party). This can be done at the home resort front desk location and you can't add more coupons than you originally had to start with. Rates will vary by package type and have not been released yet. The package still expires at midnight the day of departure and can not be extended. The packages still can't be added upon arrival and must be done three days prior to arrival just like before. This is all the information released to far. Expect more when the official announcement comes out tomorrow.
