We will also be spending Easter at the World (CSR), this is our third Easter there! A few suggestions;
If you have little ones (who still believe in the Easter Bunny) DO NOT forget some candy or stuffed animal for Easter morning! In our haste my DW and I forgot everything in 2004. The disappointment of our DD8 at the time was unbearable. She actually wanted to call her grandmother to check our house to make sure the Easter Bunny left something.
Check with the resort for activities. We visited friends at Fort Wilderness that year and they had a great egg hunt for all the children (kind of made up for forgetting the candy) and followed it up with a visit from Chip and Dale!
Ask mousekepping for towel animals. It's amazing how they can make a washcloth look like a duck, swan, bunny, etc. and it doesn't cost a thing.
See you in the Spring!
