Get a magic marker and "name" ONE of the cards (WDW1, Cruise1...) for the rest, "name" them 2,3,4,5,...etc.
Scratch off the back of the card for the last four card number and the code
On the left side of the screen: Enter the card "name" (WDW1)
Fill in the card number then the code...
Check the right side screen, make sure the name and amount of the card is correct
Under the card name and card number it says Make Primary (in blue letters) Make it primary.
Left side of the screen: put in card 2, card number, code... Check the right side of the screen the card name and amount are correct
put in card 3, card number, code... check the right side of the screen
put in card 4.......
put in card 5.......
STOP
All the slots are full, now you need to transfer to WDW1
Look at card 2, it says Transfer Balance, hit it
New screen pops up
check the information on the left side of the screen that card 2 and the amount are correct
check the information on the right side of the screen that WDW1 is correct and the transfer amount will add up correctly
Transfer
Back to main screen
Card 2 should show a balance of 0.00 and WDW1 should have the amounts of WDW1 plus card 2
Under Card 2 there is a delete button
STOP and make sure you are deleting card 2 with 0.00 balance
Delete
Repeat for cards 3,4,5
After card 5 is showing 0.00 and you deleted it, you should only have WDW1 showing on the right side of the screen with the amounts of WDW1+card2+card3+card4+card5. Do the math ahead of time to make sure you are correct.
Put a zero on cards 2,3,4,5 so you know they are zero balance.
Repeat for cards 6,7,8,.....
When you are done, take the marker and write in the corner of WDW1 the total amount the card has on it and put it a safe place. Tell at least one family member where the "safe place" is, (just in case).
