Hi Grammy! Welcome to the Rewards Board! I'm sure you'll get a thousand answers to you question.
Here are a few of mine, in order to better answer your question:
When do you plan to go to WDW; what time of year?
What special things do you have planned?
Who will you be packing for? Self, Spouse, child(ren) and age(s).
How many times have you been to WDW?
Will you be staying on site?
Will you be driving or flying?
Will you have a rental car?
Answer these and I'll send you a list of what to pack.
Have a great weekend!
