Is this your first C-section?
I only ask because I've had three, each recovery was different.
MY birth Mom had a heart attack in April after my second son was born. He was 4 weeks old. We drove from Ga to Penn to see her as we were told she was on death's bed.
Even though I didn't drive, pack or lift luggage, and only cared for the 4 week old, I bleed much more then I did at home during recovery.
Also, I pulled an area, reopened a small area- I was itching and just reached there and I scratched the healing skin - not thinking until after it hurt-

, and ended up with an infection.
DH drove, packed and managed our older child and I was exhausted with the situation. I am not one to sit or lay - I do what I need to do but would never, ever even try to go to WDW that soon after the surgery.
I'm sorry Mom, but I think it would be a very big mistake. The kids would have to slow down for you, DH would have extra work on his hands, and depending on the time of year, the temperatures would reek havoc with your surgery area.
Please reconsider your vacation time.
Also, don't forget how your after birth, hormones play with your emotions AND engorgment if b r e a s t feedng your little one.
